建立了一种绿色、简便、廉价、灵敏的离子液体固定相吸附萃取-高效液相色谱法，用于快速筛选和同时测定茶汤中的4种杀菌剂(嘧菌酯、百菌清、扑菌灵和氟虫菊酯)残留量。这种离子液体修饰的萃取纤维能够在添加表面活性剂的情况下直接从复杂的茶水基质中提取目标分析物。采用单因素一次法和正交试验法对提取工艺条件进行了考察。通过一系列实验，确定了最佳工艺条件为：10%NTF_2为包覆液，旋流时间为2分钟，L乙腈500目为分散溶剂，解吸时间为2分钟。在此条件下，将该方法应用于实际茶水中杀菌剂的检测，结果令人满意。(C)爱思唯尔有限公司发布的2017年。
A green, simple, inexpensive, and sensitive ionic liquid immobilized fabric phase sorptive extraction method coupled with high performance liquid chromatography was developed for rapid screening and simultaneous determination of four fungicides (azoxystrobin, chlorothalonil, cyprodinil and trifloxystrobin) residues in tea infusions. This IL modified extraction fiber is capable of extracting target analytes directly from complicated tea water matrices with the addition of surfactant. A series of extraction conditions were investigated by one-factor-at-a-time approach and orthogonal test. After a series experiments, the optimum conditions were found to be 10% [HIMIM]NTf2 as coating solution, 2 min vortex time, 500 mu L acetonitrile as dispersive solvent and 2 min desorption time. Under the above conditions, the proposed technique was applied to detect fungicides from real tea water samples with satisfactory results. (C) 2017 Published by Elsevier Ltd.
