摘要：

A new chelating ion-exchange resin with a spacer CH2-NH-C6H4- based on a microreticular chloromethylated styrene-divinylbenzene copolymer containing alpha-nitroso-beta-naphthol as a functional group has been synthesized. The sorption characteristics for manganese(II), iron(III), cobalt(II), nickel(II), copper(II), and zinc(II) have been investigated over the pH range 1.0-7.0. The resin is highly stable in acidic and alkaline medium. Iron(III) and cobalt(II); copper(II) and iron(III) are separated very effectively in a column operation by stepwise elution.
