灭幼脲和吡虫啉杀虫混剂的高效液相色谱分析

Determination of Dichlorbenzuron and Imidacloprid In the Mixture by HPLC

采用高效液相色谱法对灭幼脲和吡虫啉杀虫混剂进行了分析。以甲醇和水为流动相 ,μBandapakphenye色谱柱为固定相 ,在 2 5 4nm下检测 ,内标法定量分析。吡虫啉、灭幼脲线性相关系数分别为 0 9984、0 9998,变异系数分别为 0 45 %、0 5 4%。

A method for the determination of dichlorbenzuron and imidacloprid by HPLC on μBandapak phenye column and UV detector(254nm)was established.The mobile phase consists of methanol-water(63/37,V/V).Using internal standard method,the results showsed that the linear correlation of imidadoprid and dichlorbenzuron were 0 9984 and 0.9998,coefficient of variation were 0.45% and 0.54% respectively.
