Study on Bbromine Extraction from the Concentrated Seawater by Emulsion
Pages: 20-23
Year: Issue:  9
Journal: Zhejiang Chemical Industry

Abstract: 采用乳状液膜对海水中溴进行提取分离,考查了表面活性剂的用量、内水相浓度、乳水比、油内比等因素对提取性能的影响.结果表明,以民用煤油为溶剂,0.54%体积分数的L-113A为表面活性剂,内相为0.05 mol/L的Na2CO3,油内比为1:1,制乳时间为18 min,萃取接触时间为8 min,乳水比1:40,浓海水溴的提取率达到99.4%,表明乳状液膜能有效的从海水中提取溴.
