TiO2 thin films were made by dip-coating technique on the quartz bead, and heat treated at 500℃ using Titanium-naphthenate as a raw material. A refractive index of anatase phase was 2.6 and SEM morphology of surface was the shape like the skeins of thread. TiO2 thin films were installed in UV- TiO2 Photocatlytic Degradation system. They could sterilize Escherichia coli (KCTC25922) and Staphylococcus aureus (KCTC1927) perfectly about 5~7 minutes. When initial concentration were 5 ppm, 10 ppm, and 20 ppm, the 50 % degradation of Rodamin-B were 1.5 hours, 3 hours and 5 hours respectively. |
