This evaluation addresses the product quality, pollution prevention, and economic issues involved in the use of ion exchange to recover cadmium and chromium from electroplating rinse waters. Test results showed that the water returned to the rinse after ion exchange was of acceptable quality. On the cadmium line, the ion exchange resin was regenerated with sodium hydroxide solution and the regenerant was subjected to electrolytic metal recovery to recover cadmium for reuse in the plating bath. On the chromium line, the ion exchange resin was regenerated with sodium hydroxide solution and the regenerant was passed through a cation exchange resin in an effort to recover chromic acid. However, due to excess sodium hydroxide in the regenerant, chromic acid could not be recovered with the amount of resin used. The pollution prevention potential of ion exchange on the cadmium and chromium rinse water is good, especially if further testing establishes good recovery of chromic acid. Payback periods of 1 year on the cadmium ion exchange and 8 years on the chromium system are projected.
