'99Mo/99mTc Generator Based on High Radionuclidic Pure Zirconium Molybdate Gel

99Mo / 99mTc radioisotope generator was prepared using in-situ precipitated zirconium molybdate chromatographic column. Zirconium molybdate gel matrix was synthesized by precipitation of neutron activation molybdenum-99 from its solution after variety purification processes to prevent contamination of the 99mTc eluate with cross-contaminants. Greeter than 82.7 ± 0.4 % of the generated 99mTc was immediately and reproducible eluted by passing 10 ml 0.9 % NaCl solution through the 1 g zirconium molybdate-99Mo column matrix at a flow rate of 0.5 ml / min and room temperature with high chemical, radionuclide ( ≥ 99.9 % 99mTc) and radiochemical purity ( ≥ 97.7 % % as 99mTcO4-) with ph value suitable for medical uses.
