Carboxylic exchange membranes were prepared from poly(vinyl chloride)/poly(methyl methacrylate‐ co ‐divinylbenzene) (PVC) [poly(MMA‐ co ‐DVB]. Transport of nickel and copper against a concentration gradient through the membrane was investigated by using a system containing NiCl 2 or CuCl 2 aqueous solution on the left side (L) and mixed solution of NiCl 2 (or CuCl 2 ) and HCl on the right side (R) of the membrane. It was found that nickel and copper were actively transported through the membrane from the L to the R side during the first 5 h of the experiments. The rate of transport of the ions increased with increasing H + ion concentration on the R side and the initial concentration of the metals ions on both sides. The highest rate of transport was observed when 0.1 mol/L MeCl 2 on the L side and 0.1 mol/L MeCl 2 ‐0.5 mol/L HCl on the R side were used. The nickel and copper transport fractions were 34 and 24%, respectively. © 1996 John Wiley & Sons, Inc.
