Low-voltage paper electrophoretic study of ion-pair formation and electrochromatography of inorganic anions on papers impregnated with titanium (IV) tungstate.
The ion-pair formation and electrochromatographic behavior of 22 anions are studied on plain and titanium (IV) tungstate impregnated papers using 0.1 N and 1 N solutions of NaNO3, Mg(NO3)2, Al(NO3)3, Cr(NO3)3, and Co(NO3)2 as background electrolytes. The effect of ion-pair formation on the migration of anions is studied. In general, the mechanism of migration is explained in terms of adsorption, precipitation, and complex formation. A number of binary and ternary separations are achieved. In Mg(NO3)2 media, the migration is correlated with the solubility of their magnesium salts for SO3(2-), C2O4(2-), SeO3(2-), AsO4(3-), and Fe(CN)6(4-).
