Abstract
This study aimed to reveal local structures of strontium (Sr) and cesium (Cs) adsorbed on clay minerals (vermiculite and montmorillonite), which suggests stabilities of the adsorbed species of 90Sr and 137Cs in the environment. Adsorption experiments to determine solid-water distribution, XRD for interlayer distances of the clay minerals, and EXAFS for speciation of Sr and Cs were conducted. They showed that Sr and Cs formed outer- and inner-sphere complexes, respectively, in the interlayer, which explains the different degree of mobility of 90Sr and 137Cs in the environment and indicates larger contribution of electrostatic effect for Sr2+ than for Cs+.
