Abstract

A novel method was suggested for removing Th(IV) and other radionuclides from liquid media. The method consists in formation of the sorbent, fibrous cerium(IV) hydrogen phosphate, directly in the aqueous solution. The sorbent shows the highest performance in the removal of Th(IV). The sorbent can also serve as a host material for the subsequent Th(IV) disposal.
