title: Investigation of Cs(I) uptake on Beishan soil combined batch and EDS techniques.
abstract: The uptake of Cs(I) on Beishan soil (BS) was strongly dependent on ionic strength and hardly dependent on pH over the observed pH range (6-13). The foreign cations competed with Cs(I) in the following order: K(+)>Mg(2+)>Ca(2+)≈Na(+)>Li(+). The uptake of Cs(I) was a pseudo-second-order process and the activation energy, E(a), was about 2.16kJ/mol. EDS analysis suggested that the most of Cs(I) was converged on the basal plane, and a small fraction bound on the frayed sorption site. All the results suggested that ion exchange was the main approach for Cs(I) uptake on BS.
