摘要： P538 P204及其混合物从盐酸溶液中萃取Fe(Ⅲ)的平衡可分别表达为: 其表观萃取平衡常数分别为 lgKA=4.46±0.09 lgKB=3.44±0.08 lgKAB=5.47±0.10 等摩尔的P538,P204混合物有最大的协同萃取系数。

关键词: P538, P204, 萃取, 协同萃取, 铁

Abstract: The mechanisms of extraction of Fe(Ⅲ) from hydrochloric acid solution with P538,P204 and their mixture were studied.The extraction equations under the experimental condi-tions could be as follows: with the apparent extraction constants lgKA = 4.46±0.09, lgKB = 3.44±0.08, lgKAB = 5.47±0.10 respectively.The equimolar mixture of P538 and P204 showed a maximum synergistic effect on theextraction.

Key words: P204, P538, extraction, synergistic extraction, iron
