摘要
报道了 4 氯 2 氧代 3(2H) 苯并噻唑乙酸乙酯除草剂及相关化合物的反相高效液相色谱分析方法。基线分离了 4 氯 2 氧代 3(2H) 苯并噻唑乙酸乙酯及相关化合物 5个组分 ,定量测定了 4 氯 2 氧代 3(2H) 苯并噻唑乙酸乙酯和 2 羟基 4 氯苯并噻唑 ,方法的相对标准偏差RSD分别为 1.6 8%和 1.0 3% ,平均回收率分别为 10 1.0 %和 10 0 .2 % ,检测限分别为 10 .2ng和 4.
A reversed phase high performance liquid chromatographic method for analyzing 4 chloro 2 oxo 3(2H) benzothiazoleacetic ethyl ester (COBTAZAE) as a herbicide is described. COBTAZAE and the related compounds, such as 4 chloro 2 oxo 3(2H) benzothiazoleacetic acid (COBTAZAA), 2 amino 4 chlorobenzothiazole (ACBTAZ), 2 hydroxyl 4 chlorobenzothiazole (HCBTAZ), and 2,4 dichlorobenzothiazole (DCBTAZ) were well separated through a Kromasil C18(200x4.6mmID, 5μm) by using CH 3OH/H 2O/CH 3COOH(60/40/1, V/V ) as mobile phase and detection at 254 nm.The good linear relationships of the injected amount versus peak area were observed with the correlation coefficients of 0.9995 and 0.9991 for COBTAZAE and HCBTAZ, respectively. The relative standard deviation, average recovery and detection limit for determining COBTAZAE were found to be 1.7%, 101.1% and 10.2 ng, respectively, and that for HCBTAZ 1.0%, 100.2% and 4.6 ng, respectively.
