Abstract

In this work, the zeolite A/activated carbon (A/AC) composite was synthesized from elutrilithe and pitch, and the removal of Cr3+ from aqueous solutions has been evaluated. The effects of batch experiment conditions, such as solution pH, contact time and initial concentration, on Cr3+ adsorption performances were investigated. The results demonstrated A/AC exhibited effective adsorption ability for the removal of Cr3+ in comparison with elutrilithe. The adsorption isotherm data could be better fitted by Langmuir-Freundlich model. The fitted data shows that the adsorption surface is heterogeneous. Removal of Cr3+ contributes to the ion exchange of zeolite and electrostatic adsorption of activated carbon.
