Influence of humic acid functionalities on uranium complexation and influence of humic acid on uranium(VI) migration in opalinus clay

Schmeide, K.; Sachs, S.; Joseph, C.; Raditzky, B.; Bernhard, G.

Abstract

Results are reported to the influence of different humic acid functionalities (nitrogen, sulfur and phosphorus containing functionalities) on the uranium(VI) complexation, to the uranium(IV) complexation by small organic model ligands, to the sorption of uranium(VI) onto opalinus clay in the absence and presence of humic acid and to the uranium(VI) diffusion in opalinus clay in the absence and presence of humic acid.

Keywords: Uranium; humic substances; complexation; functional groups; sorption; opalinus clay
