| Abstract: | Fe and N doped carbon nanofibers (Fe-N-CNF) were prepared by electrospinning, and their degradation performance of bisphenol A (BPA) with the activation of peroxymonosulfate (PMS) was studied. The electrospinning sols were prepared by using polyacrylonitrile as the precursor, with adding FeCl3, urea, NH4Cl, and pyromellitic dianhydride. Then the sols were electrospun to obtain the precursor fibers, and after their pre-oxidation and carbonization at high temperatures, the Fe-N-CNF was obtained. The effects of Fe-N-CNF dosages, PMS dosages, initial solution pH on the degradation of BPA were investigated. The experimental results showed that the degradation efficiency of BPA was 100% within 30 min at the condition of 1 g·L-1 Fe-N-CNF, 2 mmol·L-1 PMS, initial pH 5 and the initial BPA concentration of 20 mg·L-1. The radical quenching experiments and electron spin resonance spectroscopy (ESR) results showed that O2·- and 1O2 were the main reactive oxygen species in this system. The degradation effects on a variety of organic pollutants by the Fe-N-CNF /PMS system were also studied. |
