摘要
本文使用烷基膦酸 ( PC- 88A) - CHCl3 内耦合大块液膜体系研究了 Cu( )的迁移行为。探讨了料液相 p H值、温度、载体浓度、金属离子浓度对 Cu( )迁移速率的影响。结果表明 ,增加载体浓度或升高温度 ,迁移速率明显升高 ,在 p H值为 3.5～ 5 .0温度为 2 88K～ 30 3K范围内 ,载体浓度为 5 .0 0 %～ 7.0 0 %时 ,Cu( )的迁移率可达
The transfer behavior of Cu(Ⅱ) through the bulk liquid membrane system of PC-88A-CHCl 3 was studied. The paper inquires into the effect of the pH values in external aqueous phase, PC-88A concentration, temperature and external aqueous phase concentration on Cu(Ⅱ) transport rate. The results showed that the transport rate of Cu(Ⅱ) markedly rose with the carrier concentration and temperature. The transfer rate can reach over 99% under the conditions of pH values 3.5～5.0, carrier concentration 5.00%～7.00% and temperature 288K～303K.
