Multiresidue Determination of Thifensulfuron-Methyl,Atrazine and Acetochlor in Soybeans by High Performance Liquid Chromatography

摘要：

The paper presents a new high performance liquid chromatographic (HPLC) method for the simulta-neous determination of three herbicides (thifensulfuronmethyl, atrazine and acetochlor) residues in soybeans. The methodology consists of an acetonitrile extraction and dispersive solid phase extrac-tion (SPE) purified step. Then the samples were analyzed by HPLC-UV (ultraviolet) and quantified by external standard method. Under the optimized conditions, the linear ranges of thifensulfuron-methyl, atrazine and acetochlor were 0.1-5.0 mg-L-1 with a good correlation coefficients (0.9996-0.9999). The average recoveries of three herbicides in spiked soybeans ranged from 70.2％ to 105.3％, and the relative standard deviations were between 2.32％ and 9.52％. The limit of detection was lower than 47 μg ? kg-1.
