In this paper,the electro-Fenton degradation antibiotic levofloxacin(LEV)performance was enhanced by hydrothermal acid treatment of graphitic carbon felt(GF)to increase its hydrophilicity and the number of surface defects.The acid-treated modified graphitic carbon felt(MGF)was characterized using the SEM,XRD,XPS,Raman,FT-IR,contact angle and other testing techniques.The results showed that the carboxyl group contents and the number of defects on the surface of MGF were significantly increased.Under the optimal reaction condition with a current of 0.15 A,pH=2,O2 aeration of 0.4 L/min and FeSO4 ...
