用二（２－乙基己基）磷酸酯－ＳＰＡＮ８０－甲苯乳状液膜体系研究了Ｍｎ（Ⅱ）的迁移行为，确定了完全、快速、迁移Ｍｎ（Ⅱ）的迁移行为、制乳及迁移条件，在此条件下，Ｍｎ（Ⅱ）与Ｆｅ（Ⅱ）可完全分离．
The migration behavior of Mn (Ⅱ) was studied by using di (2-ethylhexyl) phosphate-SPAN80-toluene emulsion membrane system and the migration behavior, milk production and migration conditions of Mn (Ⅱ) In this condition, Mn (Ⅱ) and Fe (Ⅱ) can be completely separated.
