摘要(Abstract)：

制备了OP-4+OP-7/苯甲醇/煤油/P204/[Omim][BF_4]/HCl微乳液体系,采用FTIR光谱以及表面张力方法对该微乳液体系的结构进行表征,并研究了该离子液体微乳液对La~(3+)的萃取行为,考察了不同的料液浓度、料液酸度、振荡时间、水乳比、温度等因素对La~(3+)萃取率的影响。结果表明:OP-4+OP-7/苯甲醇/煤油/P204/[Omim][BF_4]/盐酸体系中形成了W/O结构;少量的[Omim][BF_4]可对La~(3+)的萃取起到显著提升的作用,得到较高的萃取率;当水乳比为3∶1,振荡时间为8 min,料液浓度为0.004 mol·L-1,p H为3时,萃取率最高可达94.94%。
