目的探讨过氧乙酸复合消毒液的消毒效果及其毒性。方法利用悬液定量杀菌试验、空气消毒试验,以及动物实验法来展开研究。结果采用过氧乙酸165mg/L和过氧化氢475mg/L复合消毒液,对于悬液当中的大肠杆菌以及金黄色葡萄球菌灭杀对数分别可达到5.00与7.50;过氧乙酸4125mg/L和过氧化氢11900mg/L复合消毒液对人工污染的白色葡萄球菌灭除率可达到100%;1050mg/kg的小鼠在观察期间未出现任何中毒症状,毒副作用低。结论过氧乙酸复合消毒液对于细菌繁殖体及其芽孢均可达到十分良好的灭杀效果,同时毒副作用小,刺激性低。
Objective To investigate the disinfection effect and toxicity of peracetic acid compound disinfectant. Methods Suspension quantitative germicidal test, air disinfection test, and animal experiments to study. The results of the use of peracetic acid 165mg / L and 475mg / L hydrogen peroxide composite disinfectant for the suspension of Escherichia coli and Staphylococcus aureus killing logarithms were 5.00 and 7.50; peracetic acid 4125mg / L and too Hydrogen peroxide 11900mg / L composite disinfectant on artificial contaminated Staphylococcus aureus can be 100%; 1050mg / kg mice did not show any symptoms of poisoning during the observation period, low toxicity. Conclusion Peracetic acid compound disinfectant can kill bacteria and its spores can achieve very good killing effect, with little side effects, low irritation.
