title: Confirmation of parathion, methyl parathion and fenitrothion in biological material on thin-layer plates.
abstract: The present work describes a confirmatory procedure for the organophosphorus insecticides having a nitro group. These insecticides are reduced to corresponding amino derivatives on thin-layer plates, and the reduction product as well as the parent compound are resolved and identified by thin-layer chromatography.
