Cyclodextrin-based dispersive liquid-liquid microextraction (CD-DLLME) was developed for the determination of triazole and strobilurin fungicides in water, juice, and vinegar samples using high-performance liquid chromatography-diode-array detection (HPLC-DAD). Undecanol, which is a green solvent, was selected as the extraction solvent. A cyclodextrin aqueous solution was chosen as the dispersion solvent and demulsifier to avoid the use of a toxic dispersion solvent and eliminate the centrifugation step. Dispersion and phase separation were completed within 1 and 60 s, respectively. The linear range of this method was 1 to 100 µg L. The limits of detection were 0.3 μg L along with the preconcentration factor of 133 and enrichment factor of 124. The recovery was 83.2% to 103.2%. This pretreatment method was fast, simple, and environmentally friendly and was successfully applied to the analysis of triazole and strobilurin fungicide residues in water, juice, and vinegar samples.
基于环糊精的分散液液微萃取(CD-DLLME)结合高效液相色谱-二极管阵列检测(HPLC-DAD)被开发用于测定水样、果汁和醋样中的三唑和甲氧基丙烯酸酯类杀菌剂。十一醇,一种绿色溶剂,被选为萃取溶剂。环糊精水溶液被选为分散溶剂和破乳剂,以避免使用有毒的分散溶剂并消除离心步骤。分散和相分离分别在 1 和 60 秒内完成。该方法的线性范围为 1 至 100 µg L。检出限为 0.3 µg L,预浓缩因子为 133,富集因子为 124。回收率为 83.2%至 103.2%。这种预处理方法快速、简单、环保,并成功应用于水样、果汁和醋样中三唑和甲氧基丙烯酸酯类杀菌剂残留的分析。
