摘　　要：目的考察两种纳米二氧化钛(TiO2)喷液在净化空气过程中的抗菌、抗病毒以及降解有毒物质甲醛的作用。方法用活菌计数,乙肝表面抗原破坏以及甲醛降解率测定等方法。结果A、B两类纳米TiO2喷液对金黄色葡萄球菌、大肠杆菌的杀灭率均在99%以上,对白色念珠菌、枯草芽孢杆菌和乙肝表面抗原具有破坏作用,在8h内,能有效降解空气中的污染物甲醛。结论两种纳米TiO2喷液均能有效杀灭或抑制空气中常见的致病菌,有效降解空气中的主要污染物甲醛,并且抗菌净化效果持久。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.
