Abstract

Speciation of technetium in ground water has been studied for understanding the migration behaviour of this radionuclide in deep geological formations. A combination of free liquid electromigration, ion exchange, solvent extraction, coprecipitation and dialysis methods has been applied. Both oxic and anoxic conditions have been employed. Systems studied include leaching of sodium borosilicate glass spiked with 99-Tc and 95-Tc followed by its passage through glauconitic sand columns, and dialysis of Tc0-2 with ground water, sodium chloride, and humic acid solutions. Results indicate the presence of the pertechnetate, Tc0-4, ion as the dominating species.
