Abstract
Spectroscopic studies of polyacrylonitrile structural transformations during its alkali modification were carried out to elucidate the cause for appearance of anion-exchange groups on a fiber. The mechanisms re sponsible for appearance of both cation- and anion-exchange groups in a sorbent obtained by this method are proposed. The existing methods f or separate determination of static exchange capacities and potentiome tric titration were analyzed on the basis of the proposed mechanisms.
