Abstract

Abstract: The adsorption of gold-thiourea complex ions by activated carbon in solution hasbeen studied.The adsorption rate curves and isothems were obtained and the effects of pHvalues of the solution and foreign iOns were examined.The microwave radiation techniquewas used to desorb the gold complexes from the activated carbon. It is found to be more effective as compared with other desorption methods.

Key words: gold, thiourea, adsorption, microwave desorption
