摘要

Recyling chromium from electroplating waste sludge is attractive both economically and environmentally. Oxidizing chromium(III)-containing electroplating waste With aqueous oxidants in alkaline suspensions did not Allow completed recovery of the chromium. Hypochlorite was Potentially a suitable oxidant as it could completely oxidize a Suspension of chromium(III)hydroxide to chromate at basic pH. Form sludge, however, only up to 85/100 of the chromium was recovered; complete recovery was not achieved despite different experimental conditions and procedures.
