DOI: 10.1039/c6ra25404g
Abstract: As radioactive wastes, contaminated vacuum pump oils from tritium-processing facilities are challenging to dispose of. In this study, we investigated the mechanism of the tritium–hydrogen (T–H) exchange reaction between the tritiated water (HTO) and many… read more here.
