摘要
报导了近年来利用液膜技术从海水中提取溴的部分研究工作．采用聚醚ＦＧ７９２１和煤油形成膜体，以不同浓度的Ｎａ２ＣＯ３作内相构成乳状液膜体系，对含溴为０．０６５ｇＬ－１的海水进行快速而有效的分离提取，探索出最佳操作条件，分离效率可达９７％以上。
The technique to reeover bromine from seawater by a liquid membrane is repoted .The liquid membrane consists of pluronic FG7921 and kerosene with different concentrations of Na 2CO 3 as inner phase. The membrane can rapidly and effectively separate bromine from seawater.The optimal operating conditions are determined, in which the recovery yield reached over 97%.This technique can be applied for mass proehuing bromine in industry.
