ANALYSIS OF CESIUM RETENTION PROCESSES IN CRYSTALLINE ROCKS

Abstract

In this work, to limit the experimental uncertainties all the experiments were carried out with

different crystalline rocks but under as similar as possible chemical conditions. The effects of

several parameters as time, Cs concentration, pH and water salinity on Kd values were investigated.

Data were also analyzed with the aim of evidencing the possible differences in the sorption

behavior, caused by the different rocks’ properties (minerals content, BET area) and considering the

existence of competitive ions in solution. The new experimental data were compared with older

data obtained at CIEMAT, when available.
