Thin-layer chromatographic detection of pyrethroid insecticides containing a nitrile group

Abstract: A spray reagent for the detection of pyrethroid insecticides containing a nitrile group by thin-layer chromatography is described. These insecticides on alkaline hydrolysis yield cyanide ion, which in turn reacts with copper(II) acetate and o-tolidine in an acetic acid medium to give a blue colour. Organochlorine, organophosphorus and carbamate insecticides do not interfere. The limit of detection is about 1 microgram.

“…Using the data generated after 60-min incubation, a linear range up to 5 µg mL -1 can be obtained with the detection limit of 0.36 µg mL -1 according to 3σ rule and concentrations of fenvalerate up to 9 µg mL -1 could be detected from the (C 0 -C f )/C 0 vs fenvalerate concentration plot. The analytical performance characteristics of the proposed method are comparable with those of previous methods for the same analyte, for example thin-layer chromatography [6,7] and differential pulse polarography [10]. The detection limit of the proposed method seems to be slightly better.…”

“…Die Substanz kann anschließend durch Umsetzung mit chemischen Reagenzien auf dem gleichen Chromatogramm näher charakterisiert werden. Weitere Möglichkeiten des Pestizidscreenings mit Hilfe der Hochleistungs-Dünnschichtchromatographie (HPTLC) wurden bereits aufgezeigt und Reagenzien wurden beschreiben, mit denen mikrochemisch Pestizide charakterisiert und identifiziert werden können (Patil und Shingare, 1993).…”
