摘　　要：COD_(Cr)分析中使用的硫酸银属于重金属溶液,若直接排入下水道,对环境影响较大,而且也是对贵重金属的浪费。文章对COD_(Cr)分析废液中银的回收进行了实验研究,将废金属银回收,配制成硫酸银溶液回用于实验中,与购买的硫酸银溶液相比,误差在可接受范围内。Silver sulfate used in COD_(Cr) analysis belongs to heavy metal solution,which is of great effect on environment and waste of valuable metal. Reclamation of silver from waste solution of COD_(Cr) analysis was experimented in this article.Reclaimed silver was used to formulate silver sulfate solution and reused in experiment.Compared to silver sulfate solution purchased,the formulated solution was acceptable for its error.
