| Abstract: | A method has been developed for simultaneous determination of chlorpyrifos and phoxim in their mixture by high performance liquid chromotography（HPLC） with photo diode array（PDA） detector.The experimental conditions through continuous comparison and analysis were confirmed.Analysises were conducted in Shimpack CLC-ODS column（250 mm×4.6 mm i.d.,5μm） with mobile phase of acetonitrile-water（volume ratio 80：20） mixture.The detection wavelength was 282 nm.The relative standard deviations of the two pesticides are 1.82%～2.29%and 2.01%～3.47%respectively and the minimum determined quantities are 1.2×10~（-10）g. |
