研究了以伯胺 N1923为载体、N205为表面活性剂、煤油为膜溶剂的乳状液膜提取钨,钨的浓度由1.09×10~(-2)mol/L 降至2.72×10~(-5)mol/L 以下。
The extraction of tungsten from emulsion membrane containing primary amine N1923 as carrier, N205 as surfactant and kerosene as membrane solvent decreased the concentration of tungsten from 1.09 × 10 -2 mol / L to 2.72 × 10 -5 ) mol / L or less.
