Abstract
Binding constants of Eu(III)- and Am(III)-complexes with soil-derived humic acid were determined by solvent extraction at various pH and ion ic strength. Based on the dependence of binding constants on pH and io nic strength, stabilities of the humate complexes in land water and se awater were estimated. Speciation calculation based on the binding con stants indicated that Am(III) could combine with humic substances in n atural water system.
