用离子对高效液相色谱以外标法分析了杀鼠新玉米毒饵。毒饵用甲醇提取 3小时 ,采用Partisil- 10ODS色谱柱 ,以甲醇∶离子对溶液 (70∶30 )为流动相 ,含 0 .0 0 5M四丁基铵磷酸盐 (pH为 7.5 )的缓冲溶液为离子对溶液 ,在波长 2 84nm处测定。方法的变异系数为 1 9% (n =7) ,回收率为 95 .5 %～ 10 0 .8%。
Using ion-pair high performance liquid chromatography with external standard method to analyze the murderous new corn bait. The bait was extracted with methanol for 3 hours, and the Partisil-10 ODS column was used. The mobile phase consisted of methanol: ion pair solution (70:30), and the buffer solution containing 0.005 M tetrabutylammonium phosphate (pH 7.5) was Ion pair solution, measured at a wavelength of 2 84nm. The coefficient of variation of the method was 19% (n = 7) and the recovery was 95.5% -108.8%.
