- W2082492871 abstract "Pyridine has a synergetic effect on the extraction of iron(II) with TTA. The spectrophotometric determination of iron (7–100μg) based on this reaction is rapid, highly reproducible and reasonably selective. The optimal pH range is wide and the sensitivity is 0.012 μg/cm2 at 580 nm. The method can be applied to the analysis of natural waters. La pyridine a un effet synergétique sur l'extraction du fer(II) à l'aide de 2-thénoyltrifluoroacétone. Le dosage spectrophotométrique du fer (7–100 μg) basé sur cette réaction est rapide, très reproductible et sélectif. Le domaine de pH optimal est étendu; la sensibilité est de 0.012 μg/cm2 à 580 nm. Ce procédé peut s'appliquer à l'analyse des eaux naturelles. Pyridin zeigt einen synenergetischen Effekt bei der Extraktion von Eisen(II) mit TTA. Die auf dieser Redaktion beruhende spektralphotometrische Bestimmung von Eisen (7–100 μg) ist schnell, sehr gut reproduzierbar und weitgehend selektiv. Der optimale pH-Bereich is gross. Die Empfindlichkeit beträgt 0.012 μg/cm2 bei 580 nm. Die Methode kann bei der Analyse natürlicher Wässer angewandt werden." @default.
