A novel method based on the monolith solid-phase microextraction(SPME) coupled with high performance liquid chromatography was developed for the determination of trace benzimidazoles in foods. The preparation of poly(vinylphenylboronic acid-co-ethylene glycol dimethacrylate) microextraction monolith based on ternary porogen was synthesized by in situ technique.The characteristics of the monolith were investigated by thermogravimetric,infrared spectroscopy and scanning electron microscopy analysis.Effects of extraction solvents，extraction velocity,purification volume,desorption solvents,desorption velocity and desorption volume on extraction amount were investigated.Under the optimal conditions,the enrichment factors of SPME monolith for benzimidazoles were in the range of 1607-3015.The calibration curves of benzimidazoles showed good linear relationships in the range of 0.100-100μg/L,with detection limits of 21-33ng/L and relative standard deviations(RSD) no more than 7.4%.The proposed method was successfully applied in the determination of benzimidazoles in fish,duck,duck blood and duck liver samples，with recoveries of 75.0%-118% and RSDs of 1.6%-8.7%.The proposed method based on SPME monolith was sensitive and accurate in the trace determination of benzimidazoles in complex samples.
