Sorption of Eu(III) on Na-bentonite dispersed in sodium chloride media was studied as a function of pH via batch-type experiments. The sorption was found increased with the increasing pH. The sorption kinetics of Eu(III) on Na-bentonite in the absence and presence of different organic acids were described by pseudo-second-order model at pH 6.0 ± 0.1. The effects of different types of organic acids on the sorption of Eu(III) to Na-bentonite were extensively investigated. It was found that the concentration ratio of Eu(III) to ligand is a critical factor to the effect of an organic acid on Eu(III) sorption.
