Abstract
Chromium is potential human carcinogen is major component of various industrial effluents. Removal of chromium using various methods has been reported in the literature. Using adsorption technique chromium in the form of chromate was removed in the present study. In countries like Pakistan resources are limited and a cost effective and environmentally benign method is needed to facilitate the community. In order to reduce the effect of chromium pollution novel adsorbents with remarkable adsorption capacities were practiced during this study. Acid treated arjun nuts, beerri ptta capsule and multani mitti along with untreated amberlite IRA 410 were employed for the batch-wise removal of chromate ions from water. In depth mechanism was explored by applying various isothermal model and adsorption capacity (mg/g) of amberlite and acid treated arjun nuts revealed their remarkable potential for chromate adsorption. Time dependence and temperature effect was also studied by applying kinetics and thermodynamics model.
