摘要
研究了运用化学沉淀法回收 CODCr分析废液中银的方法 .银的沉淀经减压过滤、洗涤及高温还原而得到金属单质银 .银的回收率达 97.5 1% ,回收银的纯度为 98.5 % .
The article is telling how to recover silver from waste Liquor in CODCr Analysis by using chemical precipitation.After decompressional filtration,washery and high-temperature reduction can we get silver precipitation and the rate of recovery can reach to 97.51% and the pureness to 98.5%.
