Polyphenolic compounds as spray reagents in inorganic paper chromatography Part I

Abstract

A study of 10 members of o-hydroxybenzoyl and isopentenylated o-hydroxybenzoyl group of compounds, as spray reagents in inorganic paper chromatography, for the detection of metal ions, shows, that resacetophenone, phloroacetophenone, gallacetophenone and 5-C-prenyl gallacetophenone can act as very useful and often universal reagents. Comparative sensitivity limits with respect to Ti(IV), V(V), Mn(II), Fe(II), Fe(III), Co(II), Ni(II), Cu(II), Ce(IV) and U(VI) have been determined for these four reagents.
