Chelating sorbents containing norsulfazole and sulfadimezine fragments were prepared by modification of maleic anhydride-styrene copolymer with amines. The conditions of the Th(IV) sorption onto these sorbents were studied. The maximal sorption was observed at pH 5. The effect of various acids on the Th(IV) desorption from the sorbents was examined. The developed procedure was applied to the Th(IV) determination in water via preconcentration.
