一种复合过氧化物消毒剂杀菌效果观察

目的观察一种复合过氧化物消毒剂的杀菌效果及消毒相关性能。方法采用悬液定量杀菌试验和病毒灭活试验方法进行了实验室评价。结果该复合过氧化物消毒剂原液含过氧乙酸50 g/L与含过氧化氢50 g/L。以含50 mg/L的过氧乙酸和50 mg/L的过氧化氢该消毒液对悬液内禽致病大肠杆菌和金黄色葡萄球菌作用5 min,杀灭率均为100%。以含250 mg/L的过氧乙酸和250 mg/L的过氧化氢该消毒液对悬液内蜡样芽孢杆菌作用10min,平均杀灭率为96.71%,对新城疫病毒达到完全灭活。结论该复合过氧化物消毒剂细菌和病毒具有良好的杀灭作用。

OBSERVATION ON GERMICIDAL EFFICACY OF AN COMPOUND DISINFECTANT OF PEROXIDE

Objective To observe germicidal efficacy and disinfection-related properties of a compound disinfectant of peroxide.Methods Suspension quantitative germicidal test and virus inactivated test were used to evaluate the efficacy.Results The original solution of this disinfectant contained 50 g/L peracetic acid and 50 g/L hydrogen peroxide.The killing rates of Escherichia coli and Staphylococcus aureus in suspension exposed to disinfectant containing 50 mg/L peracetic acid and 50 mg/L hydrogen peroxide for 5 min were 100%.The average killing rate of Cerea bacillus exposed to the disinfectant containing 250 mg/L peracetic acid and 250 mg/L hydrogen peroxide for 10 min achieved 96.71%,that of Newcastle disease virus achieved 100%.Conclusion This compound disinfectant of peroxide has good efficacy on killing bacteria and virus.
