Comparison of Cs adsorption/desorption behavior between weathered biotite and the other minerals

Abstract

It is necessary to investigate the fate and the dynamic state of Cs released from the Fukushima Daiichi nuclear power plant. We conducted Cs-adsorption/desorption experiments for weathered biotite, zeolite and the other various clay minerals. The desorption experiments with low-concentrated Cs indicated that the weathered biotite fixed Cs very rigidly, whereas Cs sorbed in zeolite was easily eluted by ion-exchange.
