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 .
