| 摘要: 本文就三种典型的有机磷(膦)酸萃取剂P204、P507、P272在高氯酸盐体系中对Co(Ⅱ)、Ni(Ⅱ)萃取分离能力进行了比较. 在萃取体系有机相中,上述三种萃取剂与Co(Ⅱ)形成的萃合物均存在粉红色八面体与蓝色四面体构型转化的平衡反应. |

| Abstract: A comparative research has been carried out on the ability of separation of Co(Ⅱ)from Ni(Ⅱ)in perchlorate solution with three types of organophosphorous extractants, di-2-ethylhexyl phosphoric acid, 2-ethyl-hexylphosphinic mono-2-ethylhexyl ester and di-2, 4, 4-tritnethyipentyl phosphinic acid.There is an interchange equilibrium between the pink octahedral and blue tetrahedral extractive coordination compounds cf Co(Ⅱ)in the organic phase. |
| Keywords: organophosphorous extractant cobalt(Ⅱ) nickel(Ⅱ) |
