Fabrication of PVA/GO Nanofiber Films by Electrospinning: Application for the Adsorption of Cu2+ and Organic Dyes

In recent years, the treatment of water pollution has been a challenging and far-reaching topic. order to improve adsorption performance polyvinyl alcohol nanofibers, new nano-adsorbent graphene oxide was introduced into them in this work. The resistance stability nanofibers were improved by crosslinking glutaraldehyde. introduction GO greatly increased Cu2+, methylene blue (MB) Congo red (CR). kinetics isotherm analysis PVA/GO nanofiber film during process showed that Cu2+ MB mainly chemical adsorption, while CR physical adsorption. on line with Langmuir isothermal model, is, single molecular layer distribution active sites relatively uniform, increasing temperature more conducive Cu2+.
