经检测pH为6.5含量为5mg/L和10mg/L的不稳定二氧化氯溶液,对金黄色葡萄球菌和大肠杆菌作用5min,其杀灭率均为99.99％。当二氧化氯含量为500mg/L对枯草杆菌黑色变种芽胞作用10min,其杀灭率达99.90％以上。含25％小牛血清菌悬液对杀菌效果无明显影响。当二氧化氯含量为500mg/L作用10min,可将HBsAg抗原性破坏。1000mg/L二氧化氯溶液对不同金属片浸包72h,有基本无腐蚀或重度腐蚀作用。在室温存放7d,二氧化氯含量下降11.85％。 After the detection of pH 6.5 the content of 5mg / L and 10mg / L of unstable chlorine dioxide solution, Staphylococcus aureus and Escherichia coli for 5min, the killing rate was 99.99%. When the chlorine dioxide content of 500mg / L of Bacillus subtilis black mutant spores 10min, the killing rate of 99.90% or more. 25% bovine serum suspension had no significant effect on bactericidal effect. When the chlorine dioxide content of 500mg / L for 10min, HBsAg antigen can be destroyed. 1000mg / L chlorine dioxide solution immersed in different pieces of metal sheet 72h, there is no basic corrosion or severe corrosion. Stored at room temperature 7d, chlorine dioxide decreased by 11.85%.
