title: Preparation and properties of a new chelating resin containing 2-nitroso-1-naphthol.
abstract: A new chelating ion-exchange resin based on a macroreticular polystyrene-divinyl benzene copolymer and containing 2-nitroso-1-naphthol as the functional species has been synthesized. It is highly stable in acidic and alkaline solutions. Its sorption characteristics for V(V), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Hg(II), Pd(II) and U(VI) have been investigated over the pH range 1.0-7.0 and the exchange-capacities have been found to be generally higher than those of a similar resin containing 1-nitroso-2-naphthol.
