研究了2—乙基己基磷酸单(2—乙基己基)酯在正己烷和四氯化碳中从硝酸介质中萃取Zn(Ⅱ)的平衡,测定了萃合物组成及萃取反应平衡常数K~M,并对萃取机理作了探讨.
The equilibrium of Zn (Ⅱ) extracted from nitric acid medium with n-hexane and carbon tetrachloride by mono-2-ethylhexyl phosphate mono (2-ethylhexyl) phosphate was studied. The composition of the extract and the equilibrium constant K ~ M, and the extraction mechanism was discussed.
