摘　　要：将两亲高分子聚(甲基丙烯酸十二酯-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Cr3+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Cr3+具有较高的迁移效率.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.
