乳状液膜法迁移及分离钼(Ⅵ)的研究

Studies on Transport and Separation of Mo(Ⅵ) by Emulsion Liquid Membrane Method

采用仲胺N72 0 7为流动载体、兰 113A为表面活性剂、煤油为膜溶剂、NaOH作内相试剂的乳状液膜体系迁移分离Mo(Ⅵ )。研究了其迁移机理 ,确定了适宜的制乳、迁移分离等有关条件。在所筛选的制乳及迁移分离条件下 ,迁移分离含Mo(Ⅵ ) 10 0mg/L的水样 ,迁移率达 98 0 %以上。

The transport and separation of Mo(Ⅵ) with emulsion liquid membrane were investigated. In this emulsion liquid membrane system, secondary amine(N7207) was used as flowing carrier,Lan 113A was used as a surfactant,kerosene was used as a solvent,the inner aqueous phase composed of NaOH was the transport mechanism and conditions of emulsion liquid membrane formation, transport and separation were determined. The studies indicated that under the optimum experimental conditions more than 98.0% Mo(Ⅵ) (0.100 g/dm 3) is transported into inner phase.
