Fungicide residues. Part V. Determination of residues of chloraniformethan in grain and cucumbers by gas chromatography

Abstract

A method for determining residues of chloraniformethan {N-[2,2,2-trichloro-1-(3,4-dichloroanilino)ethyl]formamide} in grain and cucumbers is presented. After extraction with methanol and preliminary partitioning with hexane, chloraniformethan is extracted into dichloromethane, separated from interfering co-extractives by preparative thin-layer chromatography on silica gel and determined by electron-capture gas-liquid chromatography.
