In this essay the destructive rates of HBsAg, the surface antigen of HBV, exposed to different light sources and photocatalysed time on both TiO2 ceramic plate and Ni net were investigated, the effect of anti-HBV of TiO2 was discussed under different light condition.The result demonstrated that ceramic TiO2 plate has 87.50% destructive rate under high Hg lamp irradiation(8μW/cm2) after 4 hours, while the controlled normal ceramic almost had no influence to HBsAg. Also the result indicated that under indirect sunlight(20μW/cm2) for 4 hours, plate with TiO2 destroyed 93.75% of the HBsAg but the ordinary plate destroyed 87.50%.The Ni net with TiO2, when placed under ultraviolet irradiation (480μW/cm2)for 2,5,10 minutes destructive rates to HBsAg were 99.80%, 99.90%, and 100% respectively, but the controlled net without TiO2 thin film showed only 93.75% even after 10 minutes under the same ultraviolet.
