Abstract

A novel hydrothermal zirconium oxide (ZrO2) ion exchange material was successfully synthesized by hydrothermal technique. The material has been characterized using different tools such as thermal analysis (DTA-TGA), FT-IR and X-ray diffraction studies. The results show that the prepared ZrO2 is pure and with a unique shape and it belongs to the hexagonal system. Chemical resistively of the material for various media such as, water, acids and bases have been assessed. The capacity of ZrO2 ion exchanger for Na+, Cu2+, Ni2+ and Zn2+ ions at natural pH has been determined. The effect of heating treatment for ZrO2 on ion exchange capacity was studied. The sorption/ion exchange behaviour of Cu2+, Ni2+ and Zn2+ ions towards ZrO2 in dif-ferent pH media has been investigated. The distribution coefficients and separation factors were determined. Finally, Freundlich isotherms for Cu2+, Zn2+ and Ni2+ ions on hydrothermal ZrO2 ion exchanger were inves-tigated and the Freundlich isotherm constants were conduced.
