Outline of Research at the Start

The better understanding of the mechanism governing immobilization selectivity between cement related anion-exchange materials and anionic pollutants in cement matrix is still one of the main challenges for the treatment of hazardous wastes including radionuclides. The purpose of this research is to reveal the immobilization principle of various anionic species in cement and the related materials by combination of experimental observations with density functional theory (DFT) calculation.
