| Abstract: | The method of recoverty of gold from the gold-containing aquous solution have been studied. The results indicated that the adsorbed gold by poly- urethane foam filled column in a medium of 2molHCl can be desorbed with pH=4-5 HCl aguous solutions; Then gold was precipetated with the solutions of hydrogen peioxide or that of ferrous sulfate.The study supported the mechanism of ion-association between adsorbed gold and polyure-thane foam. |
