摘　　要：实验采用微波两步法合成了1-辛基-3-甲基咪唑六氟磷酸([Omim]PF6)离子液体,采用多种方法表征了离子液体的结构。研究了[Omim]PF6对模拟苯胺废水的微波萃取,考察了反应体系相比、微波反应时间、微波功率、体系pH对萃取效果的影响。结果表明,在体系相比为V离子液体:V苯胺溶液=1:8,微波反应时间为80 s,微波功率为150 W,体系pH为8的条件下,对苯胺溶液的萃取率可达99.85%,并且[Omim]PF6具有良好的再生性能。[Omim]PF6 ionic liquid was synthesized through two-step microwave reaction and ionic liquid synthesis conditions were optimized. The microwave extraction of aniline wastewater by [Omim]PF6 was discussed. The effects of phase ratio, microwave extraction time, microwave power, and pH on the extraction equilibrium were discussed. Results show that under the conditions that phase ratio is V （[Omim]PF6）：V （Aniline solution）-1：8, microwave extraction time is 80 s, microwave power is 150 W, and pH is 8, the extraction rate can be up to 99.85%. [Omim]PF6 has a good regeneration performance
