Anodic Oxidation Treatment

We investigate the effects of static and dynamic anodic oxidation treatment on the surface chemical composition and functionality of carbon fibers. During static treatment, the electrolytic surface oxidation process is performed on a spatially fixed carbon fiber bundle, while in the dynamic process a moving, continuous carbon fiber tow is oxidized. In both treatment modes electrolytic current density and treatment time were varied. Surface chemical composition and functionality of the resulting carbon fibers were analyzed by x-ray photoelectron spectroscopy. A good agreement between the chemical composition and the functionality of fibers from static and dynamic anodic oxidation treatment is found. This suggests that results from static fiber treatment in a variable, easy to handle laboratory setup can be applied to dynamic anodic oxidation process conditions on a large scale.

Biofilm Carriers

Results of our workgroups have shown that carbon fibers (CFs) are high quality biofilm carriers with well biocompatibility relative to other polymer carriers used in biofilm sewage treatment. In the present study, two kinds of microorganisms, namely, aerobic nitrifier and facultative aerobic denitrifying bacterium, were immobilized on the surface of different CFs, which the effects of specific area, functional groups and wettability on immobilization of these bacteria was studied. Results show that different microorganism require for different surface properties of CFs. Biomass of immobilized aerobic nitrifier increases with increasing specific areas, surface oxygenic functional groups and wettability of CFs. It can be immobilized more facultative aerobic denitrifying bacterium if there are proper specific areas, surface functional oxygenic group and wettability on the surface of CFs
