摘要
介绍了一种用铝置换法从实验室含银废液中回收银并进一步制备成硝酸银的方法,具有操作方便、回收率高和成本低的特点,采用该方法不仅能够有效回收实验废液中的银,解决环境污染和资源浪费问题而且可以循环使用于学生实验,为学校带来了明显的经济效益和教育意义。
The technology of extracting silver from experimental waste liquid by aluminum replacement method and preparation of silver nitrate are studied. The features of the method are operating easily, high silver recovery, low cost. The method can effectively recover the silver in wastewater, solve the problems of environmental pollution and resource waste and can be recycled in student experiment, brings economic benefits and significant for the school education
