摘要：

Two types of molecularly imprinted solid phase microextraction fibers were fabricated through sol-gel method using diazinon and isocarbophos as the templates, respectively, and were assembled together to constitute a molecularly imprinted array solid phase microextraction device. The device was then used in combination with gas chromatography for the determination of five organophosphorus pesticide residues in fruits and vegetables. The proposed method exhibited very low limits of detection, ranging from 0.002 8 to 0.043 6 μg/kg, lower than those obtained by using a single molecularly imprinted solid phase microextraction fiber. The recoveries of five analytes in spiked apple and potato samples were 78.7%-122.8%. The study showed that the molecularly imprinted array solid phase microextraction device had the advantages of high extraction efficiency, high sensitivity, good accuracy and selectivity, and high throughput, and could be suitable for simultaneous determination of multiple analytes in complex matrices. © 2021, China Food Publishing Company.
