영문 초록

The photodegradation of phenol and toluene with the Ti0₂-coated polyethylene (PE) particles were investigated in the slurry type photocatalytic reactor, changing the Ti0₂ particle sizes, initial phenol and toluene concentrations, and the oxygen flow rate. The nano-sized Ti0₂ photocatalyst particles were prepared by the diffusion flame reactor and they were coated onto PE particles by using the hybridization system for the efficient recollection of Ti0₂- coated particles after photodegradation experiments. The degradation efficiencies of phenol and toluene with the Ti0₂-coated PE particles were more than 90% after photodegradation of 80 minutes for most cases. The efficiencies of photodegradation with the Ti0₂-coated PE particles were found to be lower than those by the pure Ti0₂ particles by 50%, because of the decrease in specific surface area of Ti0₂ particles in PE particles.
