摘要

[Objective] The study aimed to determine tebuconazole residue in apples and vegetables using matrix solid phase dispersion-gas chromatography( MSPD-GC).[Method] The effects of extraction and determination conditions on the detection of tebuconazole left in apples and vegetables were analyzed,and the optimum extraction conditions were determined.[Result] The recovery rate of tebuconazole was the highest when the ratio of a sample to florisil dispersant was 1∶4,and the mixture of hexane and acetone( 1∶1) with total volume of 8 ml was as the eluant.Under the optimum conditions,the relative standard deviation( RSD) of the method was 4.9%-7.6%,and the detection limit was 0.1 μg/g,while the recovery rate of tebuconazole changed from 86.7% to 95.2%.[Conclusion] The method was simple,accurate,sensitive and applicable to the determination of tebuconazole in agricultural products.
