摘要：
A modified Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method based on the dispersive solid-phase extraction (dSPE) combined with high-performance liquid chromatography (HPLC) was developed for the determination of thiabendazole (TBZ) in environmental and food samples. Hydroxyl functionalized multiwalled carbon nanotube (MWCNT-OH) was used as dSPE material for the preconcentration of analyte. Several experimental parameters, including the amount of sorbent, extraction time, the pH and ionic strength of sample solution, and desorption conditions, were evaluated. Under optimal experimental conditions, good linearity was observed in the range of 10–1000 ng mL−1 with the correlation coefficient of 0.9962. The limit of detection and quantification were 2.6 and 8.7 ng mL−1, respectively. The present method was applied to the analysis of different environmental and food samples, and the recoveries of TBZ obtained were in the range of 92.9–103.9 % with the relative standard deviations lower than 6.5 %. The results showed that the proposed method was a rapid, convenient, and feasible method for the determination of TBZ in environmental and food samples.
