Study on Adsorption of Cu(II) in Aqueous Solution by Modified 5A Zeolite Adsorbents

Abstract

This paper investigated the effect of the modification of 5A zeolite by KCl solution for eliminating Cu2+ from aqueous solutions. The results show that the adsorbent modified with 0.5 M KCl exhibited the best performance, and the removal rate is 82.12%, the adsorption capacity is 53.1 mg/g, when the initial concentration of Cu(II) is 63.4 mg/L, In addition, the extension of the adsorption time will also increase the adsorption capacity. This indicates that KCl can effectively increase the adsorption capacity of Cu2+. It is hoped that this method can be applied to wastewater treatment.
