摘要
本文报道了无流动载体的甲苯乳状液膜体系的制备及迁移金属离子的行为,试验了当内相试剂分别为EDTA,Na_4P_2O_7,Na_2S_2O_3,HNO_3等时,改变外相介质条件,迁移铅、锌、镉、汞等金属离子的情况,对迁移机理进行了探讨。选择了适宜的乳状液膜体系,对铅、锌、镉、汞等金属离子的分离进行了研究。
A toluene emulsion liquid membrane has been prepared. Transportation behaviors of metal lons in this kind of liquid membrane system have been studied, when inner phase reagents are EDTA, Na_4P_2O_7, Na_2S_2O_3, HNO_3 etc. respectively. Transportation mechanism of the emulsion liquid membrane was discussed. Optimum conditions were selected for separation of Lead (Ⅱ),Zinc (Ⅱ),Cadmium and Mercury.
