Abstract
The complexation of thorium (IV) ions in aqueous solutions by pyoverdi ne A has been studied. On the basis of a simple model, the thermodynam ical equilibrium constant was determined and the value K-Th =(0.15+/-0 .03) M was compared with those previously obtained with uranyl ions. H owever, it is shown that the set of data obtained does not give defini te preference to this model with respect to another that involves comp lexation with 2+ charged thorium ions.
