摘要
本实验以二(2-乙基己基)磷酸酯-SPAN80-甲苯乳状液膜体系,系统研究了Zn(Ⅱ)的迁移行为。实验结果表明,在该体系中的最佳条件下,Zn(Ⅱ)以高效、快速迁入内相,并能与Hg(Ⅱ)、Fe(Ⅱ)等常见离子有效分离。对于提取、分离、富集Zn元素具有一定的理论意义和实际意义。
The transporting behaviour of Zn(Ⅱ) through the emulsion liquid membrane of bis - (2 - ethylhexyl) phosphate - span80 - oxylene was systematically investigated in the paper. The results showed that, under the optimum condition of the system, Zn(Ⅱ) entered inter phase efficiently and rapidly , and could be separated from Hg(Ⅱ) and Fe (Ⅱ) , etc. This is of both theoretical and practical significance in extracting, isolating and gathering Zn .
