Abstract :
By potentiometric study using a specific uranyl ion-selective electrode, the formation of 1:1 and 1:2 (metal:ligand) complexes of uranyl with various humic acids (HAs) was found. The conditional stability constants were calculated using the LETAGROP-ETITR program. Possible structures of the complexes are proposed. Stability constants were found to be rather high indicating that immobilized HA can be used, for example, to remove traces of uranyl from waste waters.
