本文研究了在P_(507)和P_(204)萃取钴镍体系中,有机相萃合物的组成、结构和萃取反应机理.首次发现在P_(204)萃取钴镍的有机相中存在如下取代反应:Co(HA_2)_2(HA)(H_2O)+Ni(HA_2)_2(H_2O)_2(?)Co(HA_2)_2(H_2O)_2+Ni(HA_2)_2(HA)(H_2O)证实萃合物分子结构对萃取选择性有显著影响.
In this paper, the composition, structure and extraction reaction mechanism of the organic phase complexes in the P_ (507) and P_ (204) extraction cobalt-nickel systems were studied. The results showed that the following substitutions exist in the organic phase of P_ (204) Reactions Co (HA_2) _2 (HA) (H_2O) + Ni (HA_2) _2 (H_2O) _2 (?) Co (HA_2) _2 (H_2O) _2 + Ni (HA_2) _2 Molecular structure has a significant effect on extraction selectivity.
