摘要
研究了APG1214-烷烃-戊醇-水(氢氧化钠水溶液)体系微乳液膜配方及其稳定性,APG1214-辛烷-戊醇-水(氢氧化钠水溶液)和APG1214-癸烷-戊醇-水(氢氧化钠水溶液)体系都有相当大的油包水微乳区,APG1214-癸烷-戊醇-水(氢氧化钠水溶液)体系更稳定。采用APG1214-癸烷-戊醇-水(氢氧化钠水溶液)液膜体系处理含苯酚的废水,探讨了氢氧化钠的浓度、接触时间、乳水比、油相的重复使用次数等对除酚率的影响。结果表明,含癸烷47%、水25%、APG+戊醇28%的微乳液,在静置120min时微乳液膜的破损率小于0.31%。采用APG1214-癸烷-戊醇-水(氢氧化钠水溶液)体系,接触时间为10min,乳水比为1:5,废水的pH值为4.5时,一次性除酚率不小于97%,而且油相重复使用十次,除酚率不会降低。
The formula and stability form microemulsion liquid membrane of APG1214-decane- pentanol-( aqueous NaOH) system have been studied, APG1214-octane- pentanol-( aqueous NaOH)system and APG1214-decane- pentanol-( aqueous NaOH)system have water in oil phase, APG1214-decane- pentanol-( aqueous NaOH)system is more stable, and it has also been done that different factors such as the content of NaOH in the aqueous solution, mixing time, the volume rate of microemulsion to wastewater and the times of oil phase recycl...
