摘要：

A method for the isotachophoresis determination of the pyrethroid insecticides permethrine and tetramethrine in water is described. After extracting the insecticides from samples and evaporating the solvent, alkaline hydrolysis was carried out. The degradation products, cis- and trans-dichlorochrysanthemic acid, cis- and trans-chrysanthemic acid and phthalimide, were identified and determined by means of capillary isotachophoresis. The detection limit is 0.01 mg/l-1 for both insecticides with recoveries of 80-89% and 91-99% for permethrine and tetramethrine, respectively.
