Fungicide residues. Part II. The simultaneous determination of residues of folpet, captan and captafol in selected fruits by gas chromatography

Abstract

A simple method for the simultaneous detection, identification and determination of folpet, captan and captafol is presented. After extraction into acetonitrile, these fungicides are extracted into diethyl ether-hexane, subjected to column chromatography on silica gel and quantitatively determined by electron-capture gas-liquid chromatography. A simple test for distinguishing between captan and folpet is also described.
