Electrochemical Degradation of Methylene Blue Aqueous Solution on Electrospinning Nanofibers (ESF) Electrodes

Abstract:

This study mostly investigated the influences of electrolytic conditions and the structure of electrospinning nanofibers electrodes on the degradation of methylene blue in details. For PAN and Fe/PAN electrodes, was prepared by electrospinning.It was found that the ESF electrodes with higher specific surface area, and higher mesopore percentage could be push the electrochemical degradation. As the same time, adjusted the initial pH, increased the current, and added to electrolyte also could improve the treatment effect of electrochemical degradation. After 90min of electrolysis, the color removal efficiency of methylene blue reached 97.6% at current with 100mA, supporting electrolyte of NaCl with 0.1mol/L and initial pH with 3~5. Under the same current conditions with the Pt-Fe/PAN anodes the color removal rate of degradation were higher efficiency than the other two anodes.
