摘要
文中针对实验室含银废液中银的再生利用提出了新方法。该方法由氯化钠沉淀-氨水溶解-电解-制备硝酸银等几个步骤组成,不仅能够使废液中的银得到有效回收(回收率达96.5%以上,回收银纯度达99.90%),而且可以循环使用于分析测定实验。具有操作方便、回收率高和成本低的特点,适宜于化学实验室等场合处理废液和循环利用含银试剂。
A novel method about the recycling and reuse of silver waste liquor comes from laboratory was put forward. This method is composed of several procedures, including precipitation with sodium chloride, dissolution in ammonia, electrolysis and preparation of silver nitrate. The percent recovery and the purity of recovered silver is 96. 5% and 99.90% respectively. The final product of silver nitrate can be reused in the analysis experiment determination.
