Аннотация: The present work is focused on sorption recovery of zinc (II) ions from chloride and chloride-sulfate solutions on some commercial anion exchangers with different physical and chemical structures. Initial zinc concentration was 1.0-5.0 mmol/L. HCl concentration in initial solutions was from 0.001 to 4.0 mol/L, whereas chloride-sulfate systems were investigated at molar ratios of HCl:H2SO4 = 1:1; 1:2 and 1:4. Acids concentrations were 0.001 and 2.0 mol/L. It was shown that the anion exchangers investigated possess good sorption and kinetic properties. After ion exchange recovery, zinc was effectively eluted by means of 2 M HCl. The elution results in complete zinc removal from the sorbents investigated and complete purification of solutions from zinc. Based on the data obtained, the anion exchangers Purolite S 985, Purolite A 500 and AM-2B can be recommended for zinc recovery from industrial solutions and waste water. © 2011 Elsevier B.V.
