摘要
The photocatalysis effect of nanometer TiO2 particles and TiO2-coated ceramic plate on Hepatitis B virus surface antigen (HBsAg) was investigated. The ELISA (enzyme-linked immunosorbent assay) standard method was used to assess the efficiency of TiO2 material to destroy the HBsAg. The research has shown that the suspension of TiO2 (0.5 g/L) can destroy most of the HBsAg under the irradiation of mercury lamp, with the light intensity of 0.6 mW/cm(2) at 365 nm wavelength, or under the sunlight irradiation for a few hours. TiO2-coated ceramic plates can also destroy the HBsAg under the irradiation of mercury lamp, with the light intensity of 0.05 mW/cm(2) at 365 nm wavelength or under the room daylight for a few hours.
