Abstract

The work presented illustrates the feasibility of using radiotracers with size exclusion chromatography (SEC) as a means of studying the kinetics of metal-ligand interactions in environmental systems. To simulate such systems a pre-equilibrated Eu(III)-humic acid model system was chosen in which 152mEu3+ as a radiotracer was used to study the isotopic exchange between Eu3+ and Eu(III)-humic acid complexation.
