摘要
改变传统的从含银废液中回收银的方法.首先调节废液酸度至弱碱性,在室温下加入强还原剂硼氢化钠,使其充分反应,可得到纯度达99%的银,回收率可达95%以上.
By way of regulating the acidity of silvery liquid waste to weak alkalinity first, and then adding strong reductant, after full reaction, we can obtain silver with the purity of 99%, and the rate of retrieval will be more than 95 %
