Abstract

The sorption and decontamination of carrier-free radioactive cations is studied on montmorillonite, illite and Hungarian soils. Carrier-free isotopes are desorbed from clay minerals and soils if they form stable with complexes EDTA. The quantity of complex-forming agent needed for decontamination depends on the total amount of complex-forming cations in the solution. The isotopes which do not form stable complexes are difficult to desorb. Copyright (C) 1999 Elsevier Science B.V.
