Removal of Cadmium from Wastewater Using Ion Exchange Resin Amberjet 1200H Columns

Yawei Bai, B. Bartkiewicz

Abstract

The aim of this study was to remove Cd 2+ by ion-exchange resin Amberjet 1200H in flow condition. The adsorption characteristics of metal onto the resin were accurately described by Freundlich isotherms. The ion exchange of cadmium on resin follows pseudo-second-order kinetics. Ion exchange capacities of the cadmi- um on the ion exchange resin was studied in metal solution. The capacities of sorption were 3.0 meq Cd/g, and the resin can be generated by HCl.
