Sorption of some univalent, divalent and trivalent metal ions has been studied on the hydrogen form of titanium arsenate and titanium tungstoarsenate gels as a function of initial solution concentration at pH 5–6. The effect of pH on maximum uptake (Qmax) has also been seen for some representative ions. Sorption of metal ion becomes almost negligible below pH 1.8, with the exception of monovalent cations. Rubidium ions exhibit interesting adsorption behaviour. The data have been compared with the exchange properties of these two inorganic ion exchangers, as reported earlier6,8.
