Trace metal analysis by combined thin-layer chromatography incorporating fluorescent support and ring oven colorimetry

Abstract

Clean and speedy analytical separation of microgram quantities of Pb(II), Bid(III), U(VI), and Th(IV): and Cu(II). Ni(II), Co(II), and Cd(II) from their mixed solutions has been made possible by ascending thin-layer chromatography. For the evaluation of different metal ions, the resulting delineated spots were scooped out with the help of a Mottier gadget and the collected material was transferred to the paper set on the ring oven. Separate rings were obtained for the individual metal ions and the computation of results was made possible by ring colorimetry, using PTC and other chromogenic reagents.
