Abstract
ABSTRACTTechnetium sorption properties of Fe2+-bearing minerals and different metal sulfides were studied by batch and column experiments. Pure stibnite (SbS3), pyrrhotite (FeS), pyrite (FeS2), galena (PbS) and loell ingite (FeAs2) fix Tc to a great extent (> 95 % of TcO4- starting inventory). They appear to be favourable backfill materials for redox-sensitive radionucli-des. Physico-chemical processes of fixation and possible fixation modes are discussed.
