Abstract

This report examines the nature of the adsorbed copper-ammine species in the resin phase, evaluates their stability constants and compares them with published data obtained in aqueous solution. It extends the study of the adsorption of copper by a strong acid-cation exchanger to solutions containing low concentrations of ammonia (0-0.032 M), and copper (10-lfM) and differentiates between the role of the ammonium ion and the free ammonia in the ion-exchange process.
