Abstract
The use of sorbents based on titanium(IV) oxohydroxophosphates for deep purification of liquid radioactive waste of complex chemical composition from Ag(I) and Sb(III) ions is shown to be promising. It has been established that Ag(I) cations are effectively extracted in an alkaline medium, Sb(III) cations - in an acidic region as a result of ionic substitution of H+ hydrophosphate groups for metal cations. Since Sb(III) is present in the anionic form in an alkaline medium, the Sb(III) anions are extracted as a result of ion exchange for the OH--groups of the sorption matrix.
