Summary
Systematic TLC separations, identification of cations and the determination of the limits of their identification on microcrystalline cellulose layers, incorporating glyoxal dithiosemicarbazone (H2-GDTS) as a spray reagent have been worked out. Metal-GDTS complexes have also been separated on silica gel ‘G’ support. Detection called for no spray reagent, owing to the intense and characteristic colours of the complexes.
