Abstract
A detection method was developed for benazolin residues in oil-bearing crops and its products.The oil-bearing crops and its products were extracted with acetonitrile saturated by n-hexane,degreased with n hexane saturated by acetonitrile,and refined with Florisil SPE column in order to prepare test liquids.The test liquids were analyzed by gas chromatography with electron capture detector for getting the benazolin residues in oil-bearing crops and its products.The liner relation of benazolin was good and the correlation coefficient was 0.999.The recovery rates of benazolin were between 91.2％～122.7％.The variation coefficients were between 2.23％ ～8.16 ％.The limit of detection (LOD) of benazolin was 0.005 mg/kg.The pretreatment technology of the method is suitable for oil-bearing crops and its products.This method could be accurate,sensitive,simple and rapid determination of operating benazolin residues.关键词
