| 摘 要： | 将两亲高分子聚(甲基丙烯酸十二酯一丙烯酸)作为膜稳定剂加到由Span-80、P507、煤油、液体石蜡和水等组成的W／O型乳液膜中，研究了此体系对痕量Cr^3 的迁移作用。结果表明，由于两亲高分子的空间稳定作用而导致乳液膜对Cr^3 具有较高的迁移效率。

| Abstract: | Effects of some factors on the transport ratio of trace Cr~(3+) were studied.The emulsion liquid membrane was made from an amphiphilic copolymer of lauryl methacrylate and acrylic acid as stabilizer,Span-80 as surfactant,P507 as carrier,kerosene and paraffin oil as solvent,and distilled water as internal phase.The results showed that the transport ratio of Cr~(3+) was improved greatly by the steric stabilization of amphiphilic copolymer. |
