摘要：

A silica-based ammonium molybdophosphate (AMP/SiO2) was successfully applied to remove Cs(I) from radioactive waste water in our previous study. The structure characterization of irradiated AMP/SiO2 was carried out by X-ray diffraction (XRD). The effect of the initial concentration of metal ions and acidity concentration for removal Cs(I) by irradiated AMP/SiO2 were investigated. No obvious difference was observed for AMP/SiO2 with 300 kGy absorbed dose from the XRD patterns, except the slightly shift of (110) peak toward a small angle. Relatively large distribution coefficient (8 x 10(3) cm3/g) of Cs(I) was obtained in 3M HNO3 by irradiated AMP/SiO2. The maximum adsorption capacity of AMP/SiO2 irradiated at 300 kGy was estimated as 22.4 mg/g. The loss of molybdenum from AMP/SiO2 in 3 M HNO3 with 200 kGy absorbed dose is less than 5%.
