H₂SO₄ and Maleic Anhydride Electrochemistry Modifications on Carbon Fiber and Effects on Immobilization of Microorganism in Waste Water

Abstract:

PAN-based carbon fiber (CF) was modified by electrochemistry using H2SO4 and maleic anhydride (MA) in current rearch. The CF surface morphology and natures were characterized by specific facilities, such as laser confocal microsopy (LCM), Fourier transform infrared spectroscopy (FTIR) and the degree of moisture. On the other hand, the biocompatibility nature was indicated by immobilization results of microorganisms on CF. The outcomes show that the surface hydrophilicity, oxygen-based function-groups and surface roughness of CF would contribute greatly to improve the immobilization ability of microorganisms on CF surface. And H2SO4 anodic oxidation on CF has more effect on microorganism immobilization than MA electropolymerization.
