Adsorption of Gold by Activated Carbon and Its Desorption with Microwave Technique

Department of Chemistry, Experiment Centre, Yunnan University, Kunming 650091

Received Date: 19 June 1994
Revised Date: 31 October 1994

The adsorption of gold-thiourea complex ions by activated carbon in solution has been studied. The adsorption rate curves and isothems were obtained and the effects of pH values of the solution and foreign ions were examined. The microwave radiation technique was used to desorb the gold complexes from the activated carbon. It is found to be more ef-fective as compared with other desorption methods.
