Determination of Carbendazim in Fruits Using Novel Activated Carbon Fiber Solid Phase Microextraction Coupled with Gas Chromatography / 环境与健康杂志

ABSTRACT

Objective To establish a method for determination of carbendazim(MBC) in fruits by using novel activated carbon fiber SMPE coupled with GC.Methods Carbendazim(MBC) in the fruits was determined by homemade activated carbon fiber-solid phase microextraction(ACF-SPME) coupled with GC-ECD.The conditions were optimized.Results The linear range was 1-100 ?g/L.The detection limit was 0.002 ?g/L.The recovery rates were 89%-95% with the relative standard deviation(RSD) was 5.6%.This method had successfully been applied to the determination of MBC in the fruits.Conclusion This method reveals a lower detection limit,high accuracy and needs no organic solvent,it is suitable for the determination of MBC in fruit.
