Abstract:

 Adsorption kinetics which describes the solute adsorption rate is an important characteristic in evaluating the efficiency of adsorption. The present study is aimed at studying the potential of activated carbon from the pods of wood apple in the removal of Cr (VI) from aqueous solution from its kinetic standpoint. The adsorption kinetics of Cr (VI) on both the adsorbents was found to follow first order kinetics. The values of initial rate and desorption constants (á and â) from Elovich equation shows a higher initial adsorption of Cr (VI) with increase in initial concentration and thus adsorption is found to be concentration dependent. The results of the study show that the activated carbon adsorbent prepared from pod of wood apple can be certainly used as an efficient adsorbent for Cr (VI) removal from aqueous solution.
