SYNTHESIS AND PROPERTIES OF THE NEW FIBROUS ANION EXCHANGER WITH AMINOETHYLPIPERAZINE FUNCTIONAL GROUPS
Abstract
A new anion exchanger with aminoethylpiperazine functional groups has been synthesized from polyacrylonitrile fiber. The subsequent alkylation with epichlorohydrin afforded another anion exchanger with strong base functional groups. The optimal conditions for synthesis of these ion exchangers have been found, their physical chemical and sorption properties have been investigated. Experimental data of sulfur dioxide sorption on the ion exchanger with aminoethylpiperazine functional groups show its practical applicability for air purification from acidic pollutants.
