Abstract

A method for determination of 20% P-C emulsion consisting of 18.5% phoxim and 1.5% cypermethrin pesticides is described. The sample was analyzed by HPLC with Beckman ODS column and using methanol-water (85/15,V/V) as mobile phase at flow rate of 1.0 mL/min, the elute was detected at 254nm.The relative standard deviation of this method is less then 0.36%.The linear concentration range is 1.5-300mg/L.The method is simple,rapid and accurate.
