Polymer analogous transformations of a “nitron” fiber were established and a new amino carboxylic fibrous cation exchanger FIBAN X-2 was obtained. It is shown that FIBAN X-2 is an effective sorbent of heavy and non-ferrous metals from multi-ionic aqueous solutions, regardless of the method of fiber amination. The cation exchanger obtained by amination of a “nitron” fiber in the vapor phase absorbs Mn +2 twice as much as the ion exchanger obtained by amination in the aqueous solution.
