Abstract

A carboxylic acid group containing resin with cation exchange capacity, 12.67 meq/g, has been used to remove Cu2+, Co2+ and Ni2+ ions from dilute aqueous solution. The resin had Cu2+, Co2+ and Ni2+ removal capacity, 216 mg/g, 154 mg/g and 180 mg/g, respectively. The selectivity of the resin for Cu2+ over Co2+ and Ni2+ was investigated in the presence of 1.0 M or 0.5 M sodium chloride. The resin was found to offer high capacity and selectivity for Cu2+. The sorbed metal ions (Cu2+, Co2+ and Ni2+) were easily stripped with dilute HCl. The sorbed Co2+ and Ni2+ could also be stripped with 1.0M NaCl.
