摘　　要：建立了一种基于酸性离子液体(AIL)原位取代反应的泡腾辅助分散液液微萃取—高效液相色谱法,用于测定地表水中痕量双酚类化合物。泡腾反应产生的大量CO_(2)气泡促进了萃取剂的分散,AIL发挥萃取剂和泡腾反应酸源的双重作用,避免了分散剂和额外酸源的使用。最优萃取条件为(10 mL样品):选用400 mg[BMIM][HSO_(4)]为萃取剂和酸源,150 mg Na_(2)CO_(3)为碱源,400 mg Li[NTf_(2)]为阴离子交换剂,1.5 mL丙酮为洗脱剂,NaCl含量400 mg,离子液体分离离心时间4 min。回归方程的R^(2)为0.9923~0.9991,双酚A、双酚B和双酚AF的线性范围分别为0.50~500.00μg/L、0.93~500.00μg/L和1.03~500.00μg/L,检出限分别为0.15μg/L、0.28μg/L和0.31μg/L,实际地表水样品的加标回收率为84.1%~104.6%,相对标准偏差为2.1%~4.9%。In this study,a method of acidic ionic liquid(AIL)-based in situ substitution reaction with effervescent-assisted dispersal liquid-liquid microextraction-high performance liquid chromatography(HPLC)was constructed to detect trace bisphenol compounds in surface water.A large number of CO_(2) bubbles produced by the effervescent reaction promoted the dispersion of the extractant,and AIL played the dual role of the extractant and the acid source of the effervescent reaction,avoiding the use of dispersants and additional acid sources.The optimal extraction conditions(of 10 mL water samples)were as follows:400 mg[BMIM][HSO_(4)]as the extractant and acid source,150 mg Na_(2)CO_(3) as the alkaline source,400 mgLi[NTf_(2)]as the anion exchange agent,1.5 mL acetone as the eluent,400 mg NaCl,and a centrifugation time of ionic liquid of 4 min.The regression equation yielded an R^(2) range of 0.9923-0.9991.The linear ranges for bisphenol A,bisphenol B,and bisphenol AF were 0.50-500.00μg/L,0.93-500.00μg/L,and 1.03-500.00μg/L,respectively.Their limits of detection were 0.15μg/L,0.28μg/L,and 0.31μg/L,respectively.The spiked recovery rates for real surface water samples ranged from 84.1%to 104.6%,with relative standard deviations between 2.1%and 4.9%.
