Removal of Hexavalent Chromium from sewage produced by small scale Industries in Aligarh

Sohail Ayub, Izhar Alam

Abstract


In this study, the adsorption potential of activated carbon for removal of (Cr+6) ions from effluents of electroplating areas has been investigated. The active compound onto the activated carbon surface under mild conditions. Hexavalent Chromium (Cr+6) in the wastewater under analysis is higher than the permissible limits of world health organization, BIS and CPCB at only one location Industrial Estate in Aligarh. The study involves batch experiments to investigate the effects of adsorbent dose, pH of solution & contact time on adsorption process and the evaluation of optimum conditions. In batch studies, the adsorption process has best fit to Freundlich isotherm. Freundlich adsorption isotherm model was applied to analyse adsorption data and was found to be applicable to this adsorption process. Finally, it can be seen that activated carbon was found to be more effective for the removal of (Cr+6) ions from the wastewater.
