Abstract
A novel polyoxometalate-cation exchanger, titanium(IV) molybdophosphate (TMP) has been synthesized under varying conditions. The material was characterized by X-ray diffraction, infrared spectroscopy, inductively coupled plasma and thermogravimetry techniques. Its stability was investigated in water, dilute acids, alkaline solutions, and high temperature up to 750 °C. Ion-exchange capacity and distribution coefficients (Kd) for twenty-nine radionuclides and metal ions have been determined. It was found that the TMP has high affinity for Cs+, Sr2+, UO22+, Ba2+, Pb2+, Tl+, Zn2+, Rb2+ and Zr4+ ions. The results of binary separation of metal ions showed that TMP can be potentially useful for analytical applications.
