在线监测废液中含有大量的金属银，也含有对环境污染严重的汞及六价铬。文章探讨了一种简单的实验室法回收金属银，在氨-pH9．182的标准缓冲溶液体系中，实现银的还原，得到高纯度的银粉。对废液进行了还原、沉淀、中和、吸附一系列处理后，水质达到国家排放标准。

In the online monitoring waste liquid includes the massive metal silver, also contains mercury and hexavalent chromium serious environmental pollution. The paper discussed a simple laboratory method to recover metallic silver, in ammonia-pH 9.182 standard buffer solution system, restore silver to obtain high-purity silver. As to liquid waste, reduction, precipitation, neutralization and adsorption are used. Passing through a series of processing, the water quality achieves the national emission standard.
