酰基硫代乙酰胺基螯合纳米纤维的制备及其对银离子的吸附研究

he acyl thioacetamide-group chelating nanofibers were prepared from PAN nanofibers and thioacetamide used as vulcanization agent by a combination of electrospinning and chemical grafting modification. The chelating nanofibers could adsorb Ag(I) ions from aqueous systems with big adsorption capacity and high adsorption selectivity. The functional groups on the chelating nanofibers could not only chelate with Ag(I) ions but also reduce the metal ions to increase the adsorption effect. At the same time, the obtained chelating nanofibers membrane structures can be easy to remove and recycle. Therefore, the chelating nanofibers may have potential application on the heavy metal ions wastewater treatment.
