A research on degradation of Ponceau S via TeNRs biosynthesized by Meyerozyma guilliermondii to activate PMS

In this paper, tellurium nanorods (TeNRs) were synthesized by Meyerozyma guilliermondii to activate potassium peroxymonosulfate triple salt (PMS) to degrade Ponceau S, and characterized by ultraviolet-visible spectrophotometer (UV−Vis), transmission Electron Microscope-Energy Spectrometer (TEM−EDS), Scanning Electron Microscope (SEM), X-ray diffractometer (XRD) and Fourier Infrared Spectroscopy (FTIR). The degradation effect of Ponceau S was studied. The results confirm that Ponceau S can be effectively degraded in the system of TeNRs + PMS + Ponceau S. A green synthesis of TeNRs and the mechanism of degradation of Ponceau S via TeNRs activated PMS have been proposed, which will provide new insights for environmental bioremediation and disposal of dye waste water.
