摘　　要：用离子对高效液相色谱法测定了双甲敌鼠铵盐乳油中有效成份含量。采用 Partisil- 1 0 ODS色谱柱 ,以甲醇∶离子对溶液 =80∶ 2 0 (体积比 )为流动相 ,离子对溶液为 0 .0 0 5 mol/L四丁基铵磷酸盐 ( p H为 7.5 )的缓冲溶液 ,测定波长 2 85 nm。方法在 0 .5～ 3.0 μg范围内有很好的线性关系 ,相对标准偏差为 0 .8% ( n=7) ,回收率为 98.5 %～ 1 0 0 .4%A method for the determination of ditolylacinone in emulsifiable concentrate was developed. The samples were analyzed by ion pair high performance liquid chromatography with UV detection at 285 nm. Chromatography was performed by using a Partisil 10 ODS(10 μm) column and methanol: pairing ion buffer (80∶20, v/v ) as the mobile phase. The buffer solution contains 0.005 mol/L tetrabutylammonium phosphate (pH7.5). RSD was 0.8% ( n =7), and the linearity was very good (correlation coefficient: 0.9999) in the 0.5 ~3.0 μg range. The recovery was 98.5%~100.4%.
