摘要：

In order to improve the catalytic activity and reusability of the powder catalyst and effectively remove the organic pollutants in high salinity wastewater, iron hexadecachlorophthalocyanine (FePcCl16)/polyacrylonitrile(PAN) composite nanofibers were prepared using electrospinning technology. The composite nanofibers were characterized by field emission scaning electron microscopy, transmission electron microscopy and X-ray diffraction. Carbamazepine (CBZ) was selected as the model pollutant to study the photocatalytic degradation activity of photoactivated persulfate of composite nanofibers in the presence of chloride ions. The results show that FePcCl16 was well dispersed in PAN nanofibers, and FePcCl16 molecular clustering was successfully avoided to maintain its catalytic performance. Under simulated sunlight, the catalytic activity of composite nanofibers increased with the increase of chloride ion concentration. At higher chloride ion concentrations (6.0-18.0 g/L), CBZ and its degradation products (including potentially toxic chlorinated compounds) can be completely degraded. After 5 degradation recycling tests, FePcCl16/PAN still demonstrate good catalytic degradation performance. © 2021, Periodical Agency of Journal of Textile Research. All right reserved.
