Some chelating ion-exchange resins containing ketoiminocarboxyclic acids as functional groups.
A series of ion-exchange resins containing -COCH(2)N[(CH(2))(m)COOH(2)](2) groups has been synthesized. Additional analogues were prepared by means of the reaction of the carbonyl group with phosphorus trichloride or thioglycollic acid. The properties of these resins and the selectivity for different metal ions have also been investigated.
