摘要
本文研究从含金废液中回收金,我们采用PVC—尼龙6树脂快速分离富集金,用亚硫酸钠洗脱液洗脱,用氢氧化钠、双氧水还原得到金,金的回收率可达97.7％.这一方法操作简单,易于掌握,取得了满意的结果.
We separate enriched gold quickly with PVC-nylon 6 resin, and elutewaste liquor with sodium sulfite eluent and reduce with sodalye and oxydol. Thenthe gold can be obtained and its recovery rate can reach 97.7%. This method oper-ates easily and learns easily too. The result is satisfactory.
