摘要
Ⅰ. INTRODUCTIONEsters of dithiophosphoric acid are a kind of excellent extractant for separating Co-Ni and Co-Mn. It was found that Co(Ⅱ) is easy to oxidize and to form the stable six-coordinated octahedral complex Co[(RO)PS] during extraction process. And it made back-extraction process very difficult. It was found that pydridine is able to cause substitute-reduction reaction with Co[(RO)PS]and to form Co[(RO)PS]·2Py. It is of
