This study describes the development of an acid induced dispersive liquid-liquid microextraction method based on the in situ formation of hydrophobic deep eutectic solvents for the extraction of bisphenol A and alkylphenols from environmental water and beverage samples. Hydrochloric acid altered the hydrophilic-hydrophobic state of fatty acid salts to obtain hydrophobic fatty acids, which formed hydrophobic deep eutectic solvents with analytes in situ to extract the analytes. Under optimized conditions, the limits of detection and limits of quantitation were 0.03-0.1 μg L and 0.12-0.3 μg L, the intraday and interday relative standard deviations were less than 3.9 %, and the enrichment factor was 29-32. The recoveries of bisphenol A and alkylphenols were 95.9-104.9 % and 86.9-105.0 %, respectively. The extraction process used only hydrochloric acid and fatty acid salts, and the extraction process required less than 1 min. This method has the advantages of simplicity, speed, low cost and environmental friendliness.
本研究描述了一种基于原位形成疏水性深共熔溶剂的酸诱导分散液液微萃取方法的开发，用于从环境水和饮料样品中萃取双酚A和烷基酚。盐酸改变脂肪酸盐的亲水-疏水状态以获得疏水性脂肪酸，其与分析物原位形成疏水性深共熔溶剂以萃取分析物。在优化条件下，检测限和定量限分别为0.03 - 0.1 μg/L和0.12 - 0.3 μg/L，日内和日间相对标准偏差小于3.9%，富集因子为29 - 32。双酚A和烷基酚的回收率分别为95.9 - 104.9%和86.9 - 105.0%。萃取过程仅使用盐酸和脂肪酸盐，且萃取过程所需时间不到1分钟。该方法具有简单、快速、低成本和环境友好的优点。
