| Abstract: | 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. |
