用TBP－TOPO（协同载体）、N113℃（表面活性剂）、液体石蜡（增强刑）、煤油（溶剂）和内相（1mol／LNaOH水溶液）乳状液膜体系，研究了钙（Ⅵ）的迁移富集行为，确定了用此液膜迁移分离钻（Ⅵ）的最适宜实验条件．钼（Ⅵ）在20min可迁移速率达99·65％以上。在同样条件下，一些共存金属高于如W~6+、Fe~3+、A1~2+Ca~2+Mg~2+Mn~2+Ph~2+Zn~z+Cu~2+、Co~2+、Ni~2+、Sn~2+等通过化液膜，迁移率很低或不被迁移，只有钼（Ⅵ）能被迁移富集，因此用（Ⅵ）可与这些金属离子得到很懑意的分离．它集后的溶液用分光光应法测定钼．此法已成功地应用到测定钨精矿中的痕量钼，相对标准偏差小平3．8％，结果满意．
The migration of calcium (Ⅵ) was studied with emulsion membrane systems of TBP-TOPO (synergistic carrier), N113 ℃ (surfactant), liquid paraffin (enhanced penalty), kerosene (solvent) and internal phase (1mol / L NaOH aqueous solution) Enrichment behavior, determine the best experimental conditions for the separation of drill (Ⅵ) with this liquid film migration. Molybdenum (Ⅵ) can migrate at a rate of 99.65% at 20min. Under the same conditions, some coexistent metals are higher than those of W 6+, Fe 3+, Al 2 + Ca 2 + Mg 2 + Mn 2 + Ph 2 + Zn ~ + Cu 2 + Only the molybdenum (Ⅵ) can be migrated and enriched due to the low or no mobility of Co 2 +, Ni 2 + and Sn 2 + Very deliberate separation. It sets the solution spectrophotometric determination of molybdenum. This method has been successfully applied to the determination of trace amounts of tungsten concentrate tungsten molybdenum, the relative standard deviation of Xiaoban 3.8%, with satisfactory results.
