Binary and ternary separations of heavy metals, e.g. Zn2+-Bi3+, Mn2+-Pb2+, Cd2+-Pb2+, Mn2+-Bi3+-Mo6+, and Cr6+-Pb2+-Bi3+ on columns of titanium(IV) tungstosilicate and Zn2+-Ni2+, Mo6+-Pb2+, Hg2+-Pb2+, Zn2+-Cr6+-Bi3+, and Zn2+-Ni2+-Bi3+ on titanium(IV) tungstophosphate, have been demonstrated. The adsorption and elution of important metal ions such as Mo6+, Al3+, and As3+ on titanium(IV) tungstosilicate and Hg2+, Fe3+, and Cr6+ on titanium(IV) tungstophosphate have been studied. Tita-nium(IV) tungstosilicate and titanium(IV) tungstophosphate have been used for separation and estimation of Pb2+, Cr6+, Zn2+, Mn2+, Ni3+, Fe3+, and Cd2+ in diverse real water samples such as river water, hand pump water, and industrial effluents.
