摘要
采用气相色谱法用SUBTM-5型毛细管柱,以双甲脒为内标物,NPD检测器对毒死蜱、啶虫脒和噻嗪酮3种农药制剂进行了同时定量分析。结果表明,毒死蜱的线性回归方程为y=1.570 486x+0.546 76(r=0.998 2),有效成分含量为32.58%;啶虫脒的线性回归方程为y=0.544 916x+0.859 651(r=0.998 9),有效成分含量为45.62%;噻嗪酮的线性回归方程为y=0.743 658x+1.243 762(r=0.999 7),有效成分含量为27.83%。
A gas chromatographic method for simultaneously quantitative analysis of chlorpyrifos, acetamipridid and buprofezin using SUBTM--5 capillary column, NPD detector and amitraz as internal standard was descrlbed.The results showed that the linear regression equation of chlorpyrifos was y=1.570 486x＋0.546 176 （r=0.998 2）,active constituent content was 32.58%; the linear regression equation of acetamipridid was y=0.544 916x＋0.859 651（r=0.998 9）,active constituent content was 45.62%;the linear regression equation of buprofezin was y=0.743 658x＋1.243 762（r=0.999 7）,active constituent content was 27.83%.
