摘要
以某湿法铜业公司外排含铜废水为研究对象,系统考察了煤油-LIX984-CTMAB(十六烷基三甲基溴化铵)液膜体系对含铜废水中铜的分离。考察内容主要包括料液酸度、内相酸度、搅拌时间、LIX984用量、乳化液用量、乳化剂(CTMAB)用量、膜相和内相体积比。在最优条件下,铜离子的萃取率达到95%左右。
The wastewater containing copper of this study was from a copper hydrametallurge plant. The effects of kerosene-LIX984-CTMAB（cetyl trimethyl ammonium bromide） liquid membrane systems on separation of copper in the wastewater containing copper were studied. The study mainly focused on the following factors： p H value of feed liquid, sulfuric acid concentration, stirring time, the dosage of LIX984, the dosage of emulsified liquid, the dosage of emulsifier and the volume ratio of membrane phase and internal phase. Under the optimum conditions of separation of copper in the wastewater, satisfactory results could be achieved（recovery95%）.
