Description

Zirconium tungstate as an inorganic ion exchange material has been synthesized at different conditions. The materials were characterized by means infrared spectroscopy, thermo gravimetric analysis, and X-ray diffraction techniques. The stability of the ion exchangers was investigated in acidic and alkaline media. Ion exchange properties of synthesized materials were studied by measuring the distribution coefficient for 134Cs, 85Sr, 57Co, and 152Eu radionuclides. In acidic medium, zirconium tungstate shows a high affinity for 134Cs. This result could be helpful for nuclear waste management, for waste water effluents containing 134Cs, 85Sr, 57Co, and 152Eu. The adsorption isotherm models of sorption process were calculated for 134Cs.
