Thin Layer Chromatographic Separation of Some Inorganic Ions on Sulpha Drug impregnated Layers

Abstract

Binary, ternary, quaternary and hexanary separations schemes for Co(II), Ni(II), Th(II), Fe(II), U(V), V(IV), Cu(II), As(III), Pb(II), Cd(II), Hg(II), Ag(I), Sb(III), Se(IV), Sn(IV), Ti(IV), Mo(VI), Pd(II) and Pt(IV) have been worked out by using sulphaguanidine as an impregnant on silica gel thin layer and by using the solvent system Isopropanol, ethyl acetate, acetic acid, water, DMF in the ratios (60:30:5:10:5) and (60:30:5:10:3). pH Metric studies have been made to establish the formation of complex between sulphaguanidine and the different metal ions to decide the nature of bonding and to determine their stability constants in an attempt to correlate it with chromatographic behaviour.
