| 摘 要： | 就酸度曲线、吸附速度、吸附能力和吸附反应的活化能等几个方面分别对采用SMF－453树脂吸附金银的机理进行了论述。结果表明：SMF－453树脂可以很强地吸附氰化物介质中的Au(CN)2^-and Ag(CN)2^-络合离子。吸附在树脂上的金和银均易被0.1mol/L和3％（M／V）的硫脲溶液洗脱，回收率为99％。

| Abstract: | The mechanism of gold adsorption onto SMF-453 anion exchange resin regarding the acidity curve,the adsorption velocity,the adsorption capacity and the activated energy of adsorption reaction was reported.Results indicated that Au(CN) 2 - and Ag(CN) 2 - complex anion could be strongly adsorbed onto the SMF-453 resin in cyanide medium.The gold silver loaded on the resin could be easily eluted by the solution containing 0 1mol/L HCl and 3%(w/v)thiourea solution and the 99% recovery was achieved. |
