Summary

Clean and rapid micro analytical separations of various ions in their mixed solutions have been made by the ascending TLC using quercetin (3,5,7,3′,4′-pentahydroxyflavone) as a spray reagent. For their evaluation, the visualized spots are scooped out with the help of Mottier gadget and transferred to the paper set on the ring oven. Separate rings were obtained for individual metal ions and the computation of their amounts is made possible by ring colorimetry, using suitable chromogenic reagents.

Zusammenfassung

Die exakte und rasche mikroanalytische Trennung verschiedener Ionen in deren Lösungsgemischen wurde durch aufsteigende Dünnschichtchromatographie unter Verwendung von Quercetin als Sprühreagens durchgeführt. Zur Auswertung wurden die sichtbar gemachten Flecken mit einem MottierGerät auf Papier übertragen und auf dem Ringofen bearbeitet. Für jedes einzelne Metall wurden verschiedene Ringe erhalten, die mit einem geeigneten Farbreagens behandelt zur kolorimetrischen Bestimmung dienten.
