Fabricating and Evaluating the Sterilization Effect of Composite Coal-Tar Pitch-Based Spherical Activated Carbon (TiO 2 /CB/Coal-Tar-Pitch-SAC)
Journal of Chemical Engineering of Japan(2020)
摘要
In this study, carbon black (CB) and carbon (coal-tar pitch-based spherical activated carbon (SAC)) were used to successfully fabricate composite-type SAC (CB/coal-tar-pitch-SAC), and its surface was coated with TiO2 to produce the composite material TiO2/CB/coal-tar-pitch-SAC. CB helps in decreasing the pore size of CB/coal-tar-pitch-SAC and increasing its specific surface area and total pore volume, which can be verified by the Brunauer-Emmett-Teller (BET) method. Practically, TiO2/CB/coal-tar-pitch-SAC can sterilize the bacteria present in the water. This study intensively verifies the high reusing sterilization capacity of TiO2/CB/coal-tar-pitch-SAC. The results indicate that TiO2/CB/coal-tar-pitch-SAC can effectively improve the water environment.
