Zusammenfassung
Ein einfaches Isolations- und Reinigungsverfahren wurde ausgearbeitet. Die Extraktion der Insecticide aus einer Homogenatsäule, die aus Kieselgel und Tiergewebe besteht, umfaßt zum Teil auch die Reinigung der Extrakte, da die polaren Verbindungen an die Säule gebunden bleiben. Der Mittelwert der Ausbeute des Verfahrens wurde im Modellversuch mit 14C- und 32P-markierten Insecticiden zu 90,5% festgestellt. Die Standardabweichung beträgt ± 5,1%.
Summary
A simple isolation and cleanup procedure for the determination of organophosphorus insecticides and their oxones in animal tissues has been developed. This procedure unites partly extraction of organophosphorus pesticides and their oxones with cleanup by column chromatography. Most polar coextracts remain on the column and in its further processing the eluate does not tend to form emulsion. The process has been studied on model mixtures of 32P- and 14C-labelled pesticides with tissues as well as after application of pesticides to white rats. The average recovery of the method is 90.5%, with a standard deviation of ±5.1%.
