摘　　要：提出了从人造金刚石酸洗废液中回收硫酸镍的方法，讨论了ＭｎＯ－４氧化法脱除Ｍｎ２＋及沉淀Ｎｉ２＋的条件，确定了合适的回收工艺。得到的硫酸镍产品质量符合ＧＢ６００９８５一级品的标准，且同时得到副产品ＮａＮＯ３和ＭｎＯ２．该工艺不造成二次污染，基本上达到综合利用的目的。回收工艺简单，经济效益显著。A method for recapturing NiSO_4 from the waste acid liquid which comes from the process of synthesizing diamond is presented. The conditions for removing Mn^2+ from the liquid by oxidizing Mn^2+ and by using MnO_4^- as well as for deposition of NiSO_4 are discussed. The suitable conditions for the process have been selected.The quality of the product NiSO_4 obtained by this method accords with the first class standard of GB6009-85,as by product NaNO_3 and MnO_2 are got at the same time.This process is simple and there is no additional pollution.
