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）₂PS₂] 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）₂ PS₂]₃ and to form Co[（RO）₂PS₂]₂·2Py. It is
