Abstract
PAN hollow fiber functional membrane with heavy metal ion adsorption capacity was prepared via layer-by-layer method using diazo-resin (DR). Ethylenediaminetetraacetic acid (EDTA) and graphene oxide (GO) with chelating function were used as modifier. Modification effect was studied by Fourier Transform Infrared Spectrometer (FTIR), contact angle test, scanning electron microscopy (SEM) and the copper ion adsorption capacity measurement. The result showed that EDTA and GO were successfully grafted on the surface of modified membrane and the hydrophilicity of the modified membrane increased. Roughness of membrane surface increased when the functional groups introduced on the surface. Adsorption for Cu2+ of modified membrane significantly improved.
