ABSTRACTFundamental data are provided for the potential use of hydrous TiIV-si oxide (TS) and hydrous TiIV-Zr oxide (TZ) as the solidification media of radioactive Cs+ and Sr2+. The sorption capacity for Cs+ and Sr2+, at various conditions, and the structure and the composition of the exchangers in these ionic forms, at high temperature, were investigated, followed by measuring the leaching rate from the calcined exchangers into water at room temperature. TS uptakes more Cs+ and Sr2+ than TZ does. The leaching rate from calcined TS is much lower than that from calcined TZ, due to the formation of titanium silicates of Cs+ or Sr2+. Based on these results, TS is considered to be superior to TZ, in sorption capacity, and the fixation capability of Cs+ and Sr2+, on the exchanger matrix.
