Effects of organic acids on Eu(III) sorption on Na-bentonite

Nov 01, 2014· 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.
