本文测定了25±1℃时二-(2-乙基己基)磷酸在不同稀释剂中从硫酸盐水溶液里对钙、钴(Ⅱ)的萃取,计算得到了萃取络合物中结合的自由萃取剂分子数和萃取平衡的表观常数,并讨论了溶剂对萃取的影响。
In this paper, the extraction of calcium and cobalt (Ⅱ) from aqueous solution of bis (2-ethylhexyl) phosphoric acid in different diluents at 25 ± 1 ℃ was studied. The free extraction of bound compounds was calculated The molecular constants and apparent equilibrium constants of extraction were discussed. The effect of solvent on extraction was also discussed.
