doi:10.7503/cjcu20170482

Abstract

Abstract:

Amidoxylated polyacrylonitrile(AOPAN) solution was prepared by the reaction of hydroxylamine hydrochloride and polyacrylonitrile(PAN). At the same time, the coaxial nanofibers(AOPAN@PAN) with AOPAN as shell and PAN as core was prepared by coaxial electrospinning technology. And the morphology, composition and mechanical properties of nanofibers were characterized by means of transmission electron microscopy(TEM), scanning electron microscopy(SEM) and infrared(FTIR). The results showed that the strength of AOPAN@PAN coaxial nanofibers increased with the increase of PAN dosage. The tensile strength and elongation at break of nanofibers was 3.677 MPa and 18.03% when the mass ratio of core to shell was 1∶3, and the maximum adsorption capacities of Cu^{2 +}, Pb^{2 +}, Cr$O^{2-}_{4}$ and methyl orange(MO) was 135.1, 151.2, 120.48 and 43.45 mg/g, respectively. At the same time, the concentrations of Cu²⁺, Pb^{2 +}, Cr$O^{2-}_{4}$ and MO are reduced to 0.17, 0.03, 0.06 and 0.91 mg/L after treatment with this nanofiber.
