摘要
Abstract
A gas chromatography-mass spectrometry（GC-MS） method is presented for determining trifluralin residues in aquatic products in this paper.In the method,extraction with acetone,partition with n-hexane and cleanup on a Florisil solid-phase extraction column were used for sample preparation,and quantification was performed by the external standard method.Trifluralin concentration exhibited a good linearity over the range of 5-100μg/L,with a correlation coefficient of 0.99996.The detection limit of this method was 1.0μg/kg for trifluralin.The recovery rates of trifluralin in eel,corvine,India shrimp,clams and swimming crab across the spike levels of 1.0,2.0μg/kg and 4.0μg/kg were 82.0%-93.6%.This simple and sensitive method can be applied for the determination of trifluralin residues in aquatic products.关键词
