The functionalization of the copolymer of;maleic anhydride withN;N'-methylenebisacrylamide (MaMb) obtained by;the reaction of pristine sorbent with thiocarbazide (TcMaMb) increases the density;and diversity of reactive groups;The chemical derivative strongly enhances the;sorption properties of the material for Th(IV);removal;Faster kinetics are obtained together with doubled sorption capacity at saturation;The selectivity for thorium binding from;complex synthetic solutions (especially at pH;>4) and real ore leachate (in acidic solution but;with lower sorption capacities) is enhanced by;the grafting of thiocarbazide;The readily functionalization of MaMb with thiocarbazide opens promising perspective for;the recovery of thorium from complex solutions
