| 内容記述 | The purpose of this research was to obtain basic knowledge for preventing elution of cesium from fly ash as MgCsPO4 by adding phosphate and magnesium solution. Removal experiment was carried out using fly ash or simulated eluate including stable cesium. Cesium removal rate was 40% at pH11 under almost all conditions. But, when pH exceeded a certain value, cesium removal rate was decreased. Cesium removal rate was increased with increase in added magnesium. Cesium removal rate was increased with increase in added phosphate until P/Ca=5, and then decreased. Existence of calcium increased cesium removal rate although existence of potassium did not. Solubility product constant of MgCsPO4 was obtained. Because radioactive cesium in real fly ash eluate is very small, a large quantity of phosphate would be necessary for preventing elution of cesium. This suggested that prevention of elution of radioactive cesium as MgCsPO4 could be difficult. | |||||||||||||||||
