【摘要】 建立了一种基于1-丁基-3-甲基咪唑双三氟甲磺酰亚胺盐（[Bmim][NTf₂]）和1-癸基-3-甲基咪唑双三氟甲磺酰亚胺盐([C₁₀mim][NTf₂])的疏水离子液体反胶束电膜提取（IL-RM-EME）样品前处理方法，用于环境水样中四环素（TC）的检测。支撑液膜（SLM）种类、膜孔径、电压、供相和受相溶液pH值和含盐量等对四环素的提取效率均有较大的影响，单因素条件优化结果显示，在不添加盐条件下，使用[Bmim][NTf₂]离子液体SLM、PC膜孔径为5μm、电压为30 V、供相pH=2.5以及受相pH=7.5时，IL-RM-EME对TC的提取率最高，达到77.8%，远高于中性（吐温85-异丙醇-正己烷）反胶束电膜体系（41.4%）。与传统的样品前处理方法相比，本方法具有操作简单、环境污染小、试剂消耗少和费用低等优势，在环境有机污染物检测中具有良好的应用前景。更多还原

【Abstract】 A hydrophobic ionic liquid reverse micelle electromembrane extraction（IL-RM-EME） method based on 1-butyl-3-methylimidazolium bis（trifluoromethanesulfonyl）imide（[Bmim][NTf₂]） and 1-decyl-3-methylimidazolium bis（trifluoromethanesulfonyl）imide([C₁₀mim][NTf₂]) was developed for pretreatment of tetracycline（TC） in environmental water samples in this work. The experimental results indicated that the type of supported liquid membrane（SLM）, membrane pore size, voltage, pH of donor/acceptor phase solution and salt content had great influences on the extraction efficiency of tetracycline. Under the optimal conditions of single factors, including using[Bmim][NTf₂] ionic liquid SLM components, PC membrane with pore size of 5μm, 30 V of voltage, donor phase at pH 2.5, acceptor phase at pH 7.5, and none salt added, the best extraction efficiency of IL-RM-EME to TC of 77.8%was obtained. This extraction efficiency was much higher than that of neutral（Tween 85-isopropyl alcohol-n-hexane）reverse micelle membrane system（41.4%）. Compared with traditional sample pretreatment method, the proposed method had many advantages such as simple operation, less environmental pollution, less reagent consumption and low cost. Moreover, the proposed method showed a good application prospect in detection of environmental organic pollutants.更多还原
