Abstract

A method for the determination of laurocapram and cypermethrin 2.5% EC by GC with 5% OV-101 column using Dicyclohexyl phthalate as internal standard was developed.The standard deviation for laurocapram and cypermethrin were 0.049 6 and 0.058 3.The coefficient of variation for laurocapram and cypermethrin were 4.82% and 2.29%.The recovery for laurocapram ranged between 98.58% and 101.52%,and the recovery for cypermethrin ranged between 98.65% and 104.90%.The method is convenient,rapid and accuracy.
