The retention of Eu(III), Th(IV), U(VI) and Am(III) in the alteration layer (gel layer) of precorroded simulated HLW glass is investigated by sorption experiments in water, NaCl and MgCl 2 brine as a function of the pH. In water, the sorption behaviour of the four elements shows a strong dependence...
