Study on Treatment of Chromium(VI)Wastewater by Absorption on Activated Carbon

Hongxin Wang

Abstract

Adsorption of wastewater containing chromium(Ⅵ) on activated carbon was studied.The operation conditions of dynamic adsorption had been investigated.Equilibrium time is seven hour,isothermal equation is q=0.161 ρ~1.666 1 and penetrated curve of adsorption was obtained.The adsorption isothermal equation can be represented by Freundlich isotherm and the activated carbon was regenerated.The results showed that it was successful in treating wastewater containing chromium(Ⅵ) by dynamic adsorption on activated carbon.
