摘　　要：介绍了砷化氢的毒性及危害性。传统的铜电解后液净化方法电积时不可避免地析出砷化氢 ,严重污染环境。控制阴极电势电积法彻底解决了砷化氢的析出问题 ,做到了环境治理与经济效益的统一 。This paper describes the toxicity and harm of hydrogen arsenide. Hydrogen arsenide released unavoidably during electrowinning with copper electrolyte purified conventionally pollutes the environment seriously. Release of hydrogen arsenide can be thoroughly eliminated by controlling cathode potential during electrowinning, thus improving both environment and economic benefits. So it is worth to be popularized.
