This paper is related to the elimination of Pb 2+ and Ni 2+ ions from aqueous solutions by adsorption in potassium tetratitanate doped with silica. The adsorbent was prepared in the form of pellets from potassium polytitanate (45 W%), powdered Pyrex ® glass (5 W%) and potato starch pastes (50W%), which were extruded and heat treated at 1100°C. The physicochemical characteristics...
