To simultaneously determine the enantiomers of prothioconazole and its chiral metabolite prothioconazole-desthio in water, beer, Baijiu, and vinegar samples by HPLC, a simple, fast, environmentally-friendly popping candy-assisted dispersive liquid-liquid microextraction technique was developed. A green medium-chain fatty acid (decanoic acid) and popping candy could be used as the extractant and solid dispersant respectively to avoid the use of toxic organic solvents. Decanoic acid was collected after extraction by solidification at room temperature. The linear range of this technique was from 27.1 to 1000 µg L. The limits of detection and quantification were within the ranges of 8.1-11.2 μg L and 27.1-37.3 μg L, respectively. The extraction recovery was 80.8% to 102.5% with the relative standard deviation ranged from 1.1 to 7.1%. This technique has been successfully applied to enantioselectively determine the residues of prothioconazole and prothioconazole-desthio in water, beer, Baijiu, and vinegar samples.
为了同时测定水中、啤酒、白酒和醋样品中丙硫菌唑及其手性代谢物丙硫菌唑-脱巯基的对映异构体，建立了一种简单、快速、环保的 popping 糖辅助分散液-液微萃取技术。一种绿色的中链脂肪酸（癸酸）和 popping 糖可用作萃取剂和固体分散剂，以避免使用有毒有机溶剂。癸酸在室温下通过固化进行萃取收集。该技术的线性范围为 27.1 至 1000 µg L。检出限和定量限分别在 8.1-11.2 µg L 和 27.1-37.3 µg L 范围内。萃取回收率为 80.8%至 102.5%，相对标准偏差范围为 1.1-7.1%。该技术已成功应用于水中、啤酒、白酒和醋样品中丙硫菌唑和丙硫菌唑-脱巯基残留的对映选择性测定。
