Abstract
Semicrystalline zirconyl molybdopyrophosphate (ZMPP) ion exchanger was synthesized and characterized by thermal analysis, IR spectroscopy, and X-ray diffraction and was used for preparing 137Cs/137m Ba radioisotope generator. The interaction of 134Cs radionuclides in HCl solutions was studied by batch equilibration method. The corresponding distribution coefficients were determined in relation to the acid concentration. Cesium-137 was loaded onto 1 g of zirconyl molybdopyrophosphate packed in 0.6 cm i.d. column. Elution of the generated 137m Ba was examined in relation to the chemical composition and flow rate of the eluent. Barium-137m was obtained with high and reproducible elution yield and high chemical and radionuclidic purity.
