摘要: Abstract Polyacrylonitrile/polypyrrole (PAN/PPy) core/shell nanofiber mat was prepared through electrospinning followed by a simple chemical oxidation method. The polypyrrole-functionalized mats showed selective adsorption performance for anions. interaction between heavy metal anions and polypyrrole (especially the Cr2O72− polypyrrole) during process studied. results that included two steps: one anion exchange Cl− Cr(VI), other redox Cr(VI) ions. amount related to protonation time of PAN/PPy increased as increased. Meanwhile, ions were reduced Cr(III) reaction with amino groups (from secondary amines tertiary amines). high selectivity nearly unaffected co-existing (Cl−, NO3−, SO42−) except PO43− pH change.
