摘　　要：以煤油为液膜相,与吸收液(0.4 mol/L甲酸钠溶液)和含溴原料液组成实验物系,利用聚丙烯单壳程-双管程中空纤维膜组件、聚砜中空纤维膜组件,分别实现封闭液膜和流动液膜体系,利用液膜分隔原料液和吸收液,考察含溴原料液、吸收液和煤油流量对提溴效果和传质系数的影响;讨论了两种液膜体系提溴过程的特点,并与气态膜法提溴过程进行了比较.Bromine was extracted with hollow fiber contained liquid membrane（HFCLM） and hollow fiber flow liquid membrane（HFFLM） instead of gas membrane in this paper. Kerosene, sodium formate solution （0. 4 mol/L） were used as organic phase and stripping solution respectively. Effects of flow rate of feed solution, stripping solution and organic solvent on bromine removal ratio and mass transfer coefficients were studied, and comparisons of extracting bromine with HFCLM, HFFLM and HFGM were formulated as a result.
