摘要
本文用浸取、沉淀、溶转等方法处理实验室含银废液,用两种还原法直接回收硝酸银.通过对比实验获取最佳实验途径,使AgNO3回收率达85%以上,纯度最高可为99.6%.
wastewater Containing silver was treated by using leaching, precipitation and other methods, silver nitrate was recovered directly by using two means from wastewater. By Comparison, the best experimental conditions were gained, the recovery rate is more than 85 percent, the purity exceeds 99.6 percent.
