摘  要：
建立温控辅助离子液体分散液液微萃取结合高效液相色谱-二极管阵列检测器法检测果汁中7种杀菌剂农药残留的新方法。对影响萃取效果的因素萃取剂和分散剂类型及体积、溶解温度、萃取时间和离心时间进行优化。在优化后的方法条件下,7种杀菌剂富集倍数可达64~101;方法检出限在4.3~13.0?μg/L之间;在0.02、0.05?mg/L和0.10?mg/L三个水平下加标,果汁(苹果汁、梨汁、葡萄汁、桃汁和橙汁)的平均加标回收率在70.0%~116.2%范围内,相对标准偏差均小于9.8%,能满足多种果汁中杀菌剂农药多残留检测的要求。

摘  要：
A novel method was developed for the determination of seven fungicide residues in fruit juices using temperaturecontrolled ionic liquid dispersive liquid-liquid microextraction (IL-DLLME) coupled with high performance liquid chromatography with photodiode array detection (HPLC-PDA). Parameters affecting the extraction performance such as the type and volume of extraction and dispersive solvents, temperature, extraction time and centrifugation time were studied and optimized. Under optimized conditions, the enrichment factors ranged from 64 to 101, and the limits of detection of the established method were in the range of 4.3–13.0 μg/L. The recoveries from apple, pear, grape, peach and orange juices at three fortified levels of 0.02, 0.05 and 0.10 mg/L ranged from 70.0% to 116.2% with relative standard deviations (RSDs) less than 9.8%. Therefore, this method can meet the requirements for the determination of fungicide residues in various fruit juices.
