A capillary electrophoresis method has been developed for the analysis of omethoate and dichlorvos. Response surface methodology (RSM) was used to optimize the separate conditions for simultaneous detection of omethoate and dichlorvos. The results indicated that the optimal conditions for omethoate and dichlorvos determination were; pH 7.64, SDS concentration 67.5 mM, separation voltage 19.0 KV. Quantitative linear ranges were 1.0-300 microg/mL for omethoate and dichlorvos with correlation of 0.9967 and 0.9965, respectively. The limits of detection were 0.046 microg/mL and 0.031 microg/mL for omethoate and dichlorvos, with relative standard deviations (R.S.D.) <3.6%. The value of recoveries for omethoate and dichlorvos were arranged from 94.1% to 106.0%.
已开发出一种用于分析氧乐果和敌敌畏的毛细管电泳方法。采用响应面法(RSM)优化了同时检测氧乐果和敌敌畏的分离条件。结果表明,测定氧乐果和敌敌畏的最佳条件为:pH 7.64,SDS浓度67.5 mM,分离电压19.0 KV。氧乐果和敌敌畏的定量线性范围均为1.0 - 300 μg/mL,相关系数分别为0.9967和0.9965。氧乐果和敌敌畏的检测限分别为0.046 μg/mL和0.031 μg/mL,相对标准偏差(R.S.D.)<3.6%。氧乐果和敌敌畏的回收率在94.1%至106.0%之间。
