Abstract:

Kineticsin the model system of reaction of ethyl alcohol conversion to acetaldehyde peroxidase by hydrogen peroxide in the presence of an iron porphyrin-containing biomimetic catalyst were studied. Application of such oxidation system, as shown by experimental results, meets the basic requirements of the Green Chemistry concept. The process was carried out in the gas phase at the temperature of 180°C and atmospheric pressure on per-FTPhPFe3+OH/Al2O3heterogeneous biomimetic catalyst using 20% hydrogen peroxide. As a result of the process acetaldehyde was obtained with the yield of 93.5% and selectivity of 98%(taking into account the loss).Through the experimental study of kinetic laws of ethyl alcohol peroxidase reaction, coherently synchronized nature of the mechanism of ethyl alcohol conversion to acetaldehyde by hydrogen peroxide on the surface of the biomimetic was identified. Thereby there was a need for a special approach to the kinetic modeling of this reaction.

Abstract:

The rejections of many industries (plastic, cosmetic, paper, and especially textile) are heavily loaded with dyes that have a toxicological impact dangerous on the environment. Methylen bleu (BM)  is an cationic dye widely used in the laboratory and in the textile industry. Carcinogenic and mutagenic, it is a powerful pollutant of water. And also Safranine is one of the most used synthetic  cationic dyes. It is a reddish brown powder soluble in water, which is mainly used as a food coloring in flavoring candies and biscuits. Safranine is also used to dye tannin, cotton, bast fibers, wool, silk, leather and paper.The purpose of this work is the liquid-solid extraction of cationic or anionic dyes from dilute aqueous solutions of 10 mg / l of both dyes with a zeolite material. The effect of several parameters on the adsorption performances were studied (contact time, the mass of the support, pH ...).

The results obtained are as follows:

•  The equilibrium of the adsorption was obtained after 180 min of two cationic dyes (SF and BM) with a low mass of zeolite (0.1g) and at pH = 6.5.
• The adsorption capacity of the dye by the zeolite increases slightly with the increase of the temperature from 25 ° to 55 ° C.
• The evolution of the adsorption capacity over time at different dye concentrations ranging from 10 to 200 mg / l with a maximum capacity of adsorption of the dye by the zeolite to.

• Qmax ( SF) =7,15mg/g.
• Qmax (BM) =7,36mg/g.

The study of the kinetic models confirms, on the one hand, that the adsorption of the two dyes (SF) and (BM) on the zeolite follows the pseudo-first order model, and on the other hand, that the Langmuir isotherm is the appropriate model to explain the safranine adsorption process on the zeolite.

Abstract:

The COVID-19 pandemic crisis has bestowed prima challenge for the  collection services, handling and disposal of infectious waste. There is also a large increase in the amount of single use plastics including masks, gloves, gowns and other protective equipment being produced by hospitals and individuals than usual. If not soundly management, this infected waste may lead to huge dumping, giving rise to public health risks. Therefore, individual require counselling on safely disposal of the used medical equipment also there is need of more robust systems for waste segregation, collection and management. All the medical and infectious waste should be treated non- recyclable to prevent human contact with infectious agents. The waste should  be disposed in colour waste should be color coded bins/ plastic bags or other colour coded containers with “swan neck” tied with proper labeling and date.  As per NACO guidelines infectious needle should be pretreated with 1% Sodium hypochlorite solution for at least 30 minutes for controlling the spread of HIV. Similarly, the COVID infected waste should be pretreated with virucide such as Formaldehyde, hydrogen peroxide, Potassium permanganate, Sodium hypochlorite solution etc for a specified time and sealed properly to prevent chances of infection. As the COVID-19 virus is composed of structural and non structural proteins and RNA, pre treatment with formaldehyde causes intermolecular cross-linking and disruption of cytoplasmic enzymes by reacting with amino groups of proteins. Similarly, KMnO4 reduces the bacterial and viral bioload by its oxidizing potential and Hydrogen peroxide provide virucidal effect by causing the breakage in RNA strands and ribosomes. Therefore, to prevent human infection all municipal waste should be pretreated with sanitizers and then disposed of through incineration or sanitary landfill.

Abstract:

Lignocellulosic materials are widespread in nature and cellulose represents the main component.1 Due to the high stability of this natural polymer, the depolymerisation and/or conversion into useful materials, under mild conditions, is still a challenge today.2,3 Our research group recently developed a new approach for the contemporary cellulose depolymerisation and fictionalization into bio-oil and cellulose-citrate, under short times, solvent free conditions and atmospheric pressure.4Cellulose is mixed with citric acid at the melting point of the acid. After the reaction time, bio-oil is extracted with a common organic solvent, while esterifies cellulose is collected as a solid. The open air system and the three acidic functionalities of citric acid lead cellulose depolymerisation.  The obtained oil is composed mainly of furan compounds, recovered in excellent yields. Chemical characterization of this bio-oil was carried out. Cellulose hydrolysis is accompanied by an etherification reaction and the product in the form of cellulose-citrate was also collected in high yields and characterized.

His current research work is on ‘A new and sustainable approach at combating environmental pollution from textile/leather effluents in Nigeria’s growing Industries’.

Abstract:

The various processes used in the textile processing industry contribute its major portion to the environmental pollution. The discharge of highly coloured waste is not only aesthetically displeasing, but it also interferes with the transmission of light and upsets the biological processes which may then cause the direct destruction of aquatic life present in the receiving stream. A small amount of dye in water (10-50mg/L) is highly visible and reduces light penetration in water systems, thus causing a negative effect on photosynthesis. Escalating costs of effluent treatments due to increasingly stringent governmental regulations pose a major economic problem for the textile industry. The most effective means to curb these costs is waste minimization at the source by optimizing application processes. This itself is achieved by using some carefully chosen heterocyclic disperse dyes which were synthesized in our laboratory. Some novel 2-aminothiophenes were prepared from cyan acetates and a range of 1,3- dicarbonyl compounds such as, o-acetoacetotoluidide, 4-chloroacetoacetanilide, and o-acetoacetanisidide using the Karl-Gewald one-pot technique.

Abstract:

Green house emissions leading to environmental issues, declining petroleum reserves and energy security concerns have promoted the current exploration of sustianable green options. This includes conversion of wastes to energy as well as to platform chemicals for the chemical and polymer industries. Hydrothermal treatment of wet biomass waste opens up the possibilities of combined fuel production and wastewater treatment in both industrial and densely populated areas where large amounts of wet waste materials are available. In this study, we proposed an integrated process where the digestate from anaerobic digestion of lignocellulosics can be transformed into valuable products. Firstly, the wet solids of the digestate are converted into phenolic compounds, a key building block for the preparation of polymers and resins, by hydrothermal liquefaction (HTL). Thereafter, the generated waste aqueous stream, a by-product of the HTL process, is subjected to hydrothermal gasification (HTG) to produce gaseous fuel - hydrogen and methane (i.e., hythane). To facilitate these thermochemical transformations, we prepared a series of novel iron catalysts doped on potassium feldspar. These synthesized cheaper catalysts provided high yields of phenolics with high selectivity for phenol and 4-ethylphenol. The aqueous stream comprised mainly of lactic acid, glycolic acid and glycerol. Hydrothermal gasification of this by-product was evaluated using Ru/C, Ru/Al₂O₃ and La/Ce₂O₃ catalysts. Ru/C and La/Ce₂O₃ gave high yields of hythane with minor amounts of C2-C3 hydrocarbons, CO and N. Overall, the integrated process resulted in the production of energy, chemicals and re-usable water.

Abstract:

n recent years, the study of modified-TiO2based electrodes has gained great attention to help improve its photo-electrochemical performance. Modifications with metals [1,2], non-metals [3,4], transition metals [5,6] and rare-earth metals [7,8]have been studied; however, research in alkali-modified TiO2is limited when compared to the aforementioned strategies. Owing to their low first ionization potentials, alkali metals supposed toreduce the total work function of TiO2, which can be an effective way to improve the performance of titania-based catalysts[9]. Herein, we investigatethedesign and characterization ofefficient sodium-modified TiO2photo-electrodes readily prepared by the electrochemical anodization of titanium metal followed by soaking treatment in aqueous solution containing quantitative NaOH alkaline medium.The crystalline properties revealed no change in the main peak positions and shapes of pristine TiO2which signifies that the existence of sodium did not affect the crystalline structure of TiO2; the modification was only confined to the surface of the nanotubes. Our analysis of the photo-electric properties showed that thesurface modified photo-catalysts exhibited an almost threefold increase in their photocurrent response (0.66 mA cm-2) relevant to the unmodified TiO2(0.22 mAcm-2) under 1 sun intensity; these feature were ascribed to the former’s remarkable charge separation and mobility.

Abstract:

Hierarchical porous carbon (HPC) monolithic with 3D network has received considerable attention due to their potentially technological application as candidates for electrochemical energy storage devices such as capacitors, lithium ion batteries, solar cells, sorbent for toxic gas separation and greenhouse gas capture for their well-defined pore dimensions and topologies. Synthetic polymer based hierarchical nanostructured carbons are particularly attractive for their consistent pore dimensions which can be adjustable on long length scales, so that diffusibility of guest species could be improved through its unique hierarchical pores. N-doped HPC monoliths exhibit multifaceted features such as tunable textural properties, excellent thermal and chemical stability, which are remarkable physicochemical properties that are answerable for micro/nanostructured porous carbons perfect candidates for emerging substrates in nanotechnology science.A two-step synthetic method has been developed to achieve functionalized nanoporous carbons via cross-linked polymer precursors, which are prepared by Friedel-craft alkylation and pyrolysis as showen in fig. 1. Nitrogen-doping proves to be an effective method for reinforcing the CO₂ adsorption capacity of carbon-based adsorbents, although it remains a great challenge to reach a fit doping level of nitrogen (N) and a high porosity in a porous carbon simultaneously. Herein, a facile method that enables the fabrication of ordered microporous nitrogen-doped porous carbon .monolith with a content of 4.6 wt% N, which employs poly (H-BINAM) as precursor. Through chemical activation, high microporosity is generated and gives birth to a monolithic structured porous nitrogen-doped carbon. This material exhibits a remarkable CO₂ adsorption capacity (6.74 mmol g-1 at 273 K and 4.27 mmol g-1 at 298 K under 1 bar), and an extraordinarily excellent CO₂/N₂ selectivity (153), which is calculated from the single-component adsorption isotherms based on Henry’s Law. This value exceeds the CO₂/N₂ selectivity of thus mentioned for carbon-based adsorbents including diverse nitrogen doped ones, whose attributes are largely associated with the unusually high N-content as well as the partial graphitic framework.

Markiewicz and co-supervision of dr Jacek L. Kolanowski. His research interests include microwave assisted organic synthesis, amides, green chemistry, natural product, pharmaceutical chemistry.   
 

Abstract:

Amide bonds are among the most widely abundant and fascinating types of linkages in organic synthesis and nature. They constitute the backbone of peptides and proteins and are important elementary linkages in many natural products and polymers. In addition, thanks to their stability in biological environments, they are often used in the construction of various drugs, insecticides, nutraceutics and chemical tools to study and modify biology. We demonstrate a microwave-assisted method for the direct solvent-free synthesis of amides from amines and carboxylic acids. This high efficiency, robustness, short reaction times, solvent-free and additional reagent-free method provides a major advancement in the development of an ideal green protocol for amide bond formation. The amide product isolation procedure is simple, environmentally friendly, and is performed with no need for chromatographic purification of secondary amides thanks to high yields. This methodology generates a limited amount of wastes, and a catalyst can be easily separated. The reactions are carried out in an open microwave reactor and allow the corresponding amides to be obtained in a fast and effective manner when compared to other procedures of the direct synthesis of amides from acids and amines reported so far in the literature.

Abstract:

Chemistry is very much required and responsible for industrial development and technological advancement. Green chemistry¹ is nothing but an extension of chemistry principles to serve the sustainability of the environment.It has the potential to address the challenges threatening the sustainable civilization.It is a set of 12 principles given by Paul Anastas and John Warner to serve the society with a modern version of chemistry which is less toxic less hazardous, highly efficient and non-polluting.²Unfortunately, the education system especially in developing countries is not very enthusiastic and welcoming towards acceptance of green chemistry in their curriculum. In many countries, students, as well as teachers, are not even aware of the philosophy and the applications of green chemistry in daily life. They don’t know its benefits in industrial development.Therefore, it is quite an unfortunate situation and a challenging one at the same time.Green chemistry does not feature yet in any K12 curriculum in India and students Start learning about it the first time at the college level only. The only direct reference to environmental chemistry topics the closest to green chemistryis found in the syllabi of K12 schools but still there is a lot of confusion Between these 2 terms.Therefore it is the need of the day that K12 chemistry curriculum allows sufficient space for fundamental principles of green chemistry and its applications which not only will be helpful to the teenage students in their day-to-day learning but also will be an added advantage to them in becoming a responsible citizen as well as a seasoned professional.In the present talk, I would try to discussthe need and the necessity of greening of chemistry curriculum at K12 level. I'm sure It would be beneficial for not only students but also the teachers as well.

Abstract:

Plastics bring a lot of of positives to the society due to the properties they could bring, like low weight, chemical resistance, transparency, strength, barrier properties, etc. And consequntly they can be used in wide range of products and applications. The downside of using plastic is the impact it currently has on environment, due to use of fossil resources for its production, CO2 impact during production, but also due to end-of-life and people behavioral effects, like waste in environment, landfill or incineration. Various technology solutions are being sought to minimize these negative effects, while maintaining the positive aspects. Examples are bio-based building blocks and polymers, mechanical and chemical recycling.BioBTX has developed technologies that enable the conversion of both biomass and end-of-life materials into platform chemicals, i.c. aromatics, especially BTX (Benzene, Toluene, Xylenes). These are the basis of 40% of all polymers produced worldwide.Applying this technology allows achievement of circularity and sustainability targets, like CO₂ reduction, minimization of use of fossil resources, lower waste by making chemical building blocks from current waste streams form agriculture, plastics, composiites, etc.In the presentation examples will be given on the flexibility of the technology and its impacton products, performance and environment.

Abstract:

Energy is the first and foremost essential factor for modern developmental activities, such as movement of goods and services, driving the industrial machines and ensuring agricultural production. Energy plays a pivotal role in our daily lives. Today energy scarcity is everywhere all over the world. Day by day the energy crisis is becoming more and more dire, on the other hand natural resources is being consumed at an alarming rate. Our natural environment is being degraded in numerous ways due to unplanned human activities. If the deterioration of the natural environment is continued in such a manner there is a possibility that earth will no longer be suitable for human survival. Scientists, politicians and social activists are paying serious attention to discovering possible new arena of energy sources as well as implementing new technology to save our environment for future generations. Alternate sources of energy are an important research field in today’s world. A great deal of research and development has focused on biomass, solar, wind, bio fuel, biodiesel, geothermal, to name a few. These alternate energy sources of energy have certain limitations; some are not technically sound, others are not economically viable or environmentally friendly. Waste Technologies LLC (WTL) has developed a ground breaking technology in the conversion of waste plastics into liquid hydrocarbon fuel. WTL technology is capable of converting almost all types of abundant waste plastics into hydrocarbon fuel that can power any internal combustion engine. WTL is expanding its unique technologies and building commercial faculties in all over the world.

Abstract:

Most of the energy around the world comes from non-renewable sources, including coal, petroleum, oil and natural gases. Microbial fuel cells are an alternative source of generating electricity using microorganisms on biomass. Paw-paw is an example of biomass and commonly known as papaya fruit. It contains sugar and other ingredients with sufficient chemical energy that can be converted  into electrical energy by means of redox reaction. The generation of electricity from waste pawpaw fruits and peels using microbial fuel cells, is one of the approach to meet the population demand for energy. The conversion of waste pawpaw into electricity would not only produce electricity but will also serve as one of the  means of recycling waste that is causing environmental pollution. The graphite used for the electrodes we obtained from waste finger batteries. The results obtained from this research shows that the voltage and current produced from the 20 kg paw-paw waste was capable of lighting a 2V bulb. The decrease in voltage and current with time was as a result of decrease in the organic matter contents of the substrate used. The dissolved Oxygen (DO). Biochemical oxygen Demand (BOD) and Chemical Oxygen Demand (COD) decreased with increase in the duration of the of energy production. It has therefore shown that this fruit waste can be used to generate electricity. It is therefore recommended that more study should be carried out on production of electricity from fruit waste.
