133Cs NMR and XPS investigation of cesium adsorbed on clay minerals and related phases
133Cs MAS NMR and Cs XPS were used to study the adsorption of Cs on kaolinite,
montmorillonite, corundum, and gibbsite from 0.1 N and 0.01 N CsCl solutions. XPS spectra
for all samples except gibbsite contain strong signals associated with Cs 3d3/2 and 3d5/2
photopeaks. This result indicates that minerals without exchangeable cation sites have a
tendency to sorb Cs on surfaces and along grain boundaries, although less than 1 mol% Cs
is observed on these surfaces. Multiple surface or interlayer sites for Cs cannot be resolved …

Abstract 133Cs MAS NMR and Cs XPS (electron spectroscopy) were used to study the
adsorption of Cs on kaolinite, montmorillonite, corundum, and gibbsite from 0.1 smallcap˜ N
and 0.01 smallcap˜ N CsCl solutions. XPS spectra for all samples except gibbsite contain
strong signals associated with Cs 3d3/2 and 3d5/2 photopeaks. This result indicates that
minerals without exchangeable cation sites have a tendency to sorb Cs on surfaces and
along grain boundaries, although less than 1 mol% Cs is observed on these surfaces …
