Abstract

Although TiO₂ exhibits a small fluoride ion exchange capacity, it was found that titanium hydroxide, Ti(OH)₄, can exchange fluoride ion with large saturation capacity of 1.60 m ̇ mol/g. Although the H₂PO₄^- interferes with the F^- exchange, the amount of F^- exchange of Ti(OH)₄ was hardly changed by the coexistence of Cl^-, NO₃^-, and SO₄^2-. The capacity for F^- exchange was almost unchanged over 4 times repetition of ion-exchange and desorption and furthermore, the elution of Ti was negligibly small. Consequently, Ti(OH)₄ is expected to be a new inorganic F^- exchanger for the removal of fluoride ion from wastewater.
