摘要

A method using liquid chromatography and a single mix-mode solid-phase extraction cleanup for the simultaneous analysis of thiabendazole [2-(1,3-thiazol-4-yl)-lH-benzoimidazole], carbendazim [(methyl N-(1H-benzoimidazol-2-yl)-carbamate)] and 2-aminobenzimidazole (1H-benzimidazol-2-amine) in concentrated fruit juices is described. The three fungicides were isolated from the samples and concentrated by solid-phase extraction on Oasis MCX cartridges. The determination was performed by liquid chromatography with a diode array, detecting at 288 nm. In this method, the average recoveries from blank control juice samples spiked in a concentration range of 0.01 0.10 mg/kg were in the range of 81-95%, with relative standard deviations below 8%. Detection limits and limits of quantification were 4 μg/kg and 10 μg/kg, respectively, for each fungicide. Real juice samples were analyzed by the proposed method. The results were compared to those from liquid chromatography-tandem mass spectrometry.
