Abstract

Abstract A high pressure liquid chromatographic (HPLC) method is described for the simultaneous determination of folpet, piperonyl butoxide, and pyrethrins in aerosol pesticide formulations. The aerosol propellants are removed from the can and the remaining components are determined by HPLC, using an U1-trasphere 5 μm ODS reverse phase column and a UV detector at 254 nm. Recoveries for the 3 components are greater than 98%.
