摘要
目的 对高铁酸钾的消毒效果进行实验研究。方法 观察一定浓度高铁酸钾对不同种类微生物悬液的消毒作用。结果 10～ 4 0mg/L高铁酸钾作用 5min对大肠杆菌、金黄色葡萄球菌的杀灭率均为 10 0 % ,对白色念珠菌的杀灭率 >99 5 0 % ,此作用条件下未观察到其对枯草杆菌黑色变种芽孢的杀灭作用 ;16 0mg/L高铁酸钾作用 30min未见对乙肝病毒表面抗原的灭活作用。结论 在一定作用条件下高铁酸钾对细菌繁殖体有良好的杀灭作用 ,对真菌也有一定的杀灭作用 ,但未见其对细菌芽孢及乙肝病毒表面抗原的灭活作用。
Objective In order to known the germicidal efficacy of potassium ferrate solution.Methods Suspension and quantitative bactericidal tests were carried out.Results At 20℃ the solution containing potassium ferrate 10-40?mg/L and with 5-minute contact time could kill 100% of Escherchla coli and Stophylococcus aureus in suspension and its solution with 5-minute contacting time could kill over 99.50% of Candida albicans in suspension.But the solution containing 40?mg/L and with 5-minute contacting time could not kill spores of Bacillus var.niger.At 20?℃,the solution containing 160?mg/L and with 30-minute contacting time could not destroy the antigenicity of HBsAg.Conclusion Potassium ferrate could kill bacteria under certain conditions and could kill fungus to some extent,but without efficacy on bacteria spare and HBsAg.
