Abstract:
Objective This paper has discussed the antibacterial、 antiviral and degrading poison property of TiO2 nanometer spray in air cleaning. Methods Viable count was carried out, the inactivation on hepatitis B antigen (HbsAg) and the degradation of formaldehyde were detected. Results The results demonstrated that the inactivation to Staphylococcus aureus, Escherichia coli were over 99%. Bacillus subtilis var. niger, Candida albicans and hepatitis B antigen(HbsAg) were inactivated to a certain extent. The spray may be used for degrading the formaldehyde in the indoor air. Conclusions These two kinds of TiO 2 nanometer spray may, to a certain extent, inactivate the pathogenic bacteria and HbsAg, and may degrade formaldehyde.
