| 中文摘要 |
| 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289K～303K、载体浓度为5.00%～7.00%时,Pb(Ⅱ)即可快速并完全迁移. |
| 英文摘要 |
| The transfer behavior of Pb(Ⅱ) through the bulk liquid membrane system of PC 88A CHCl3 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. |
