Stability of technetium in the moderate oxidation states in acidic media

Maciej Chotkowski, Andrzej Czerwiński

Abstract


Technetium is one of the most important radionuclides in the spent nuclear fuel in context of reprocessing, storage and long term disposal. Spectroelectrochemical studies on the redox behavior of this element are presented and possible pathways of pertechnetate ions reduction are discussed. The stability of technetium (III/IV) species are discussed.


Keywords
