Synthesis, characterization and application of zinc augmented aminated PAN nanofibers towards decontamination of chemical and biological contaminants

摘要

A novel amine functionalized Polyacrylonitrile (PAN) based electrospun nanofibers mat decorated with zinc (A/Zn/PAN) was synthesized, characterized and evaluated for the decontamination of chemical and biological contaminants. The loading capacity of the chromium (Cr (VI)) and congo red (CR) dye on A/Zn/ PAN nanofiber mat were approximately 23 and 25 mg/g, respectively. Various adsorption parameters like pH, kinetics, dose rate were ascertained by using batch adsorption experiments. Using XPS studies a suitable mechanism has been proposed for the adsorption. The nanofiber mat was found to be effective in inhibiting the growth of Escherichia coli, and Staphylococcus aureus bacterial strains.
