[18001-26-19] Study on the characterization and performance of removing cesium by geomaterials
キーワード：Cesium, radioactive waste, adsorption, geomaterials, fly ash
In this study, adsorption is chosen as the method to remove Cs. The geomaterials were prepared as adsorbent by using fly ash and slag as raw materials and activated by alkali activator. The materials were characterized by XRD, SEM-EDS, BET surface area, pore volume and pore size analysis. Adsorption isotherms of Cs onto the geomaterials was investigated with varying initial concentrations under optimum experiment conditions.Kinetic models and adsorption isotherm models are used to describe the mechanism involved in the adsorption process.
