摘要： 用硫脉浸出法提取金、银具有速度快、毒性小,再生净化工序简单等优点.用活性炭自硫脉浸金溶液中吸附金是极为有效的方法,但吸附后不易洗脱,我们研究了活性炭对金一硫脉络离子的吸附及微波解吸附.

关键词: 金, 硫脲, 吸附, 微波解吸

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
