Zusammenfassung

Vergleichsanalysen zur Bestimmung von Permethrin aus Holz ergaben, dass sich sowohl Extraktion mit Methanol im Ultraschallverfahren als auch Soxhlet-Extraktion mit Ethylacetat gut eignen, um Permethrin aus behandeltem Holz zu lösen. Verschiedene andere Extraktionsverfahren führen zu Minderbefunden. Zur quantitativen Bestimmung von Permethrin können sowohl Hochdruckflüssigchromatographie als auch Gaschromatographie eingesetzt werden.

Abstract

Parallel experiments to analyse permethrin in treated timber demonstrated that extraction with methanol by sonication as well as Soxhlet extraction with ethyl acetate are suitable methods to dissolve permethrin from treated wood. Several other extraction methods yield low recoveries. Quantification of permethrin can be realised by either high performance liquid chromatography or gas chromatography.
