| Abstract: | To investigate the mechanisms of tritium persistence in clay minerals,three types of clay soils(montmorillonite,kaolinite and illite) and tritiated water were used in this study to conduct the tritium sorption tests and the other related tests.Firstly,the ingredients,metal elements and heat properties of clay minerals were studied with some instrumental analysis methods,such as ICP and TG.Secondly,with a specially designed fractionation and condensation experiment,the adsorbed water,the interlayer water and... |
