Abstract

X-ray diffraction and high-resolution transmission electron microscopy showed that cesium ions (Cs<sup>+</sup>’s) in a vermiculite clay formed a segregated monoionic layer in the interlayer spaces. Each ion was fixed simultaneously at the centers of hexagonal rings in the upper and lower silicate tetrahedral sheets. No Cs<sup>+</sup> was eluted even when Cs<sup>+</sup>–vermiculite was kept at 80 °C for 48 h in the presence of a large excess of Al(NO<sub>3</sub>)<sub>3</sub> or [Co(NH<sub>3</sub>)<sub>6</sub>]Cl<sub>3</sub>.
