用磷酸三丁酯（ＴＢＰ）－ＬＭＳ－２－磺化煤油乳状液膜体系，在乳状液膜内水相直接制备结晶碳酸钇讨论了外水相酸度、内水相试剂浓度、盐析剂浓度、外水相中钇的浓度以及载体浓度、表面活性剂浓度对结晶的影响找到了制备结晶碳酸钇的最佳条件在最佳条件下得到的结晶碳酸钇，经灼烧转化的氧化钇含量大于９９９％，回收率为９０％以上
With the TBP-LMS-2-sulfonated kerosene emulsion liquid membrane system, crystalline yttrium carbonate was directly prepared in the aqueous phase of emulsion liquid membrane. The effects of external aqueous phase acidity, internal aqueous reagent concentration, salting-out agent Concentration, the concentration of yttrium in the outer aqueous phase and the concentration of the carrier and surfactant concentration on the crystallization found the best conditions for the preparation of crystalline yttrium carbonate obtained under the best conditions of crystalline yttrium carbonate, after burning conversion of oxidation Yttrium content of more than 99 9%, the recovery rate of 90%
