Interaction of humic acid with actinides: Influence of heteroatomic functional groups other than carboxylic groups

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

The role of heteroatomic functional groups other than carboxylic groups on the interaction behavior of humic acids (HA) with actinides is widely unconsidered. Applying synthetic HA the influence of reduced sulfur functionalities on the U(VI) complexation and the Np(V) reduction by HA was studied. Reduced sulfur functionalities have been identified as complexing and redoxactive sites in HA.
