摘要
研究了在以烷基膦酸为载体的液膜中Pb(Ⅱ )的液膜迁移行为 .探讨了料液相 pH值、温度、载体浓度、金属离子浓度对Pb(Ⅱ )迁移率的影响 .实验结果表明 ,Pb(Ⅱ )的迁移率随温度和载体浓度的升高而逐渐增大 .当外水相 pH值控制在 2 8～ 4 0、温度为 2 89K～ 3 0 3K、载体浓度为 5 .0 0 %～ 7.0 0 %时 ,Pb(Ⅱ )即可快速并完全迁移 .
The transfer behavior of Pb(Ⅱ) through the bulk liquid membrane system of PC 88A CHCl 3 was studied. The study include to analysis the effect of Pb(Ⅱ) transport rate of the pH values in external aqueous phase, carrier concentration, temperature and external aqueous phase concentration. The results showed that the transport rate of Pb(Ⅱ) markedly raised with the carrier concentration and temperature. The transfer rate can reach 100% under the condition of pH values 2 8～4 0, carrier concentration 5 00%～7 00% and temperature 289K～303K.
