摘要
将钨酸钠尾液进行预调pH值后,利用超滤膜的特性进行WO3与SO42-、Cl-分离,并浓缩WO3,同时将溶液中的SO42-、Cl-通过多次透析除杂,并研究不同条件下超滤膜的渗透通量及除氯率与除硫率及钨损。
Using the characteristics of ultrafiltration membranes to separate WO3 from SO42-and Cl- after pre-adjusting the pH of the sodium tungstate tail liquid, and concentrate the WO3. At the same time,SO42-and Cl- in the solution were removed by multiple dialysis. As we can study the removal rate of Chlorine and Sulfur,the permeation flux of ultrafiltration membrane and the Tungsten loss under different conditions.
