| Abstract: | The adsorption and separation properties of gold and silver by D 001 CC strong acid resin from weak acid solution have been investigated . The results show that resin can effectively adsorb gold thiourea complex ions and silver thiourea complex ions.The saturated adsorption capacity is as high as 68.8 mg(Au)/g-sesin and 99.1 mg(Ag)/g sesin.The gold and silver absorbed on the resin can be guantitatively eluted by the solution of N aCN N aOH and buffer solution of H 3BO 3 -NaOH with solution of Na 2 S 2O 3. The gold and silver have been separated. |
