摘要：
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 μg/mL for omethoate and dichlorvos with correlation of 0.9967 and 0.9965, respectively. The limits of detection were 0.046 μg/mL and 0.031 μg/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%.
