Dissociation kinetics of rare earth element complexes

A Comparison of the Dissociation Kinetics of Rare Earth Element Complexes with Synthetic Polyelectrolytes and Humic Acid... 

Here, we report on dissociation kinetic studies of the rare earth elements Sm(III) and Eu(III) from PAA and HA. The solution chemistry of both metals is essentially identical, and they are frequently used as analogs for trivalent actinide elements. We have studied the rare earth dissociation kinetics from different size fractions of PAA and HA using ion exchange and ligand exchange methods. The differences in metal labilities for complexes of the two polyelectrolytes and the effect of polyelectrolyte molecular weight on binding times are discussed in the context of possible polyion-cation interactions in these systems.
