摘要
研究了由表面活性剂、油性溶剂及盐酸水溶液制备的油包水 (W/O)型微乳液对稀土离子RE3 +从料液相 (水相 )提取到微乳相中的行为 ,初步考察了表面活性剂浓度、水乳比、温度及载体浓度对提取率的影响 ,从而确定了适于稀土离子提取的微乳体系及提取条件。
A kind of water-in-oil(w/o)microemulsion was prepared with the surfactant oil solvent and hydrochloric acid.The extracting behavior of RE 3+ has been studied from the RE 3+ feed.The effects of the concentration of surfactant,the volume ratio of oil to water,the experimental temperature and the mobile carriers have been studied.The optimum conditions of microemulsion and extracting RE 3+ have been obtained.
