Abstract
The report concerns research performed to develop anion-exchange membranes for the removal of copper, cadmium and zinc, as their complex cyanide anions, from cyanide process electroplating rinse waters by Donnan dialysis, and to fabricate and evaluate a prototype Donnan dialyzer utilizing these membranes. Results obtained from the study indicate that anion-exchange membranes with transport properties suitable for the removal of metal complex anions can be prepared by irradiation grafting of polymer films. Evaluation of the membranes showed that ion transport rates are directly proportional to ion-exchange capacity. A series of technical problems with ion-exchange membrane preparation and with operation of the prototype dialyzer precluded successful completion of the follow-on project.
