Abstract
The distribution of Cu2+ and Ni2+ ions in an aqueous solution — flax fiber heterophase system was investigated. The specific surface area of the sorbent and the average pore radius were determined. The sorption isotherms were processed in terms of the Langmuir and Freundlich models and the theory of volume filling of micropores. It was shown that the sorbent behaves as a weakly acidic cation exchanger with the α-hydroxycarboxyl groups as sorption sites. The modification of flax fiber with polyvinylpyrrolidone allows one to noticeably increase its sorption properties.
