| 摘 要： | 本文研究了自制的均相渗析阴膜对对钛白废液中废酸的回收效果，实验考察了膜的交换容量，苯环卤含量，废液中的组分的相对浓度等因素对渗析过程的影响，结果表明，用自制的阴膜回收膜废液中的Ｈ２ＳＯ４是可行的，能实现Ｈ２ＳＯ４与其他成分如ＦｅＳＯ４，Ｔｉ（ＳＯ４）２的良好分离，其分离系数分别不低于２６．０和５１．０。

| Abstract: | In this paper, we have conducted the research of Sulfuric acid recovery from titanium white waste liquor by self-manufactured anion exchange membrane. The effect of some factors, such as ion exchange capacity, content of benzyl-halogen and the relative compositions of the liquor was experimentally investigated on the membrane dialysis process. The results show that the recovery technology is practically feasible, which can realize a good separation of Sulfuric acid from FeSO 4 and Ti(SO 4) 2 and the separation coefficients are expected to exceed 26.0 and 51.0 for static runs, respectively. |
