乳状液膜法分离高钼低钨料液中钨钼的研究

Separation of tungsten and molybdenum in solution containing high concentration of molybdenum and low concentration of tungsten by emulsion liquid membrane

根据钼资源利用中钼料液含少量钨的具体实际，对此类高钼低钨料液采用以三烷基氧化膦（ＴＲＰＯ）为载体、ＮａＯＨ为反萃试剂的液膜体系来分离钨钼考察了影响钨钼分离的诸因素，得到了分离钨钼的最佳操作条件在此条件下，钼的浓度为００５２１ｍｏｌ／Ｌ，ＷＯ３与Ｍｏ的质量分数为１０％的料液经一级间歇液膜过程。

Using trialkyl phosphoine oxide (R 3PO,R=C 6～C 8) as carrier and sodium hydroxide solution as internal aqueous phase, separation of tungsten and molybdenum in solution containing high concentration of molybdenum and olw concentration of tungsten by emulsion liquid membrane system was studied.The effects of several factors on the transport of tungsten and molybdenum were investigated. A set of optimum operating condition was obtained.One-stage emulsion liquid membrane process was carried out to separate molybdenum form tungsten under the optimum operating condition, and 100% pure molybdenum was obtained in the internal aqueous phase.
