Abstract:
利用1-乙烯基-3-己基咪唑溴盐与氧化石墨烯之间的静电吸引力,将其附着于氧化石墨烯表面,然后经聚合、还原,制备了聚合离子液体-石墨烯复合材料,用SEM、FT-IR、UV-vis等对复合材料进行了表征.将聚合离子液体-石墨烯复合材料用于固相萃取(Solid-phaseextraction,SPE)的吸附剂,结合高效液相色谱,研究了此吸附剂对环境水样中4种有机磷农药的萃取性能.对影响SPE效率的参数(吸附剂量、上样体积、上样流速、洗脱剂和洗脱剂体积)进行了优化.在优化条件下,杀螟松、对硫磷、倍硫磷和辛硫磷在5~200μg/L有良好的线性关系,相关系数(R2)为0.9908~0.9995.将本方法用于环境水样中有机磷农药的测定,加标回收率在80.0%~110.0%之间,RSD<4.5%(n=3).结果表明,与石墨烯相比,聚合离子液体-石墨烯复合材料作为SPE吸附剂,能降低萃取过程中的团聚现象,对目标物的萃取效能更高;本方法可用于环境水样中有机磷农药残留的测定.
