摘要
研究用溶剂萃取技术从含微量金的废液中回收金。试验结果表明 ,含氧萃取剂及二烷基乙酰胺 (A10 1)均是萃金的有效萃取剂。用A10 1为萃取剂 ,二乙苯为稀释剂 ,金的回收率达 97%以上 ,并获得含金 99 99%的商品金锭。处理后的废水可并入常规的污水处理厂处理 。
The gold recovery from the waste solution containing trace gold by the technology of solvent extraction is investigated The experimental results indicate that oxyextractants and A101 are effective to extract gold The gold recovery is as high as 97% with the A101 as extractant and diethylbenzene as diluent, and the gold product with the purity of 99 99% is obtained The wastewater can be disposed in the normal wastewater treatment system to correspond to the environmental requirement
