Abstract
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.
