摘　　要：建立了高效液相色谱法检测杀螟丹的分析检测条件。采用甲醇-水(体积比60∶40)的混合溶液为流动相,用盐酸(1mol/L)调pH至3.0,流速为0.8mL/min,检测波长为220nm。方法检测线性范围为1.25～80mg/L,决定系数为0.9989,检出限为0.1mg/L,相对标准偏差为0.73%。A simple, sensitive, rapid and accurate HPLC method was developed for determination of cartap. The mobile phase methanol/water（60：40, by vol）, pH 3.0 was adjusted with hydrochloric acid at flow rate=0.8 mL/min, UV detection provided by SPD-20A detector was set up at 220 nm. Linearity was observed in the concentration range 1.25-80 mg/L with a correlation coefficient of 0.9989 and the limit of detection （LOD）=0.1 mg/L, the relative standard deviation of the equipment was 0,73%.
