Comparison of the americium(III), neptunium(V) and uranium(VI) sorption onto kaolinite in the absence and presence of humic acid

Schmeide, K.; Krepelova, A.; Sachs, S.; Bernhard, G.

Abstract

We studied the sorption of Am(III), Np(V) and U(VI) onto kaolinite under aerobic and anaerobic conditions as a function of pH, ionic strength and actinide concentration in a series of batch equilibrium experiments. These actinides were selected as representatives of actinides in different oxidation states. Furthermore, we studied the influence of humic acid on the actinide sorption.

Keywords: americium; neptunium; uranium; sorption; humic acid; trivalent; pentavalent; hexavalent
