稳定性二氧化氯消毒液杀菌效果试验观察

目的观察一种稳定性二氧化氯消毒液的杀菌效果。方法采用悬液定量杀菌试验和物体表面现场消毒试验进行杀菌效果观察。结果用含40 mg/L二氧化氯消毒液对悬液内金黄色葡萄球菌、大肠杆菌、铜绿假单胞菌作用5 min,杀灭对数值均>5.00,对悬液内白色念珠菌作用5 min,杀灭对数值均>4.00。对物体表面自然菌作用10 min,杀灭对数值>1.00。结论该稳定性二氧化氯消毒液具有较好的杀菌效果。

STUDY ON GERMICIDAL EFFICACY OF A STABLE CHLORINE DIOXIDE DISINFECTANT

Objective To observe the germicidal efficacy of a stable chlorine dioxide disinfectant.Methods Suspension quantitative germicidal test and field disinfection trial were used to carry out experimental observation.Results The killing logarithm values of Staphylococcus aureus,Escherichia coli and Pseudomonas aeruginosa exposed to the solution containing chlorine dioxide 40 mg / L for 5min were > 5.00 and that of Candida albicans exposed for 5 min was > 4.00.In field trial,the killing logarithm value of nature bacteria on the surface of objects wiped with the disinfection solution containing chlorine dioxide 40 mg / L for 10 min was > 1.00.Conclusion The stable chlorine dioxide disinfectant has good bactericidal effect.
