摘要
目的:了解一元固体二氧化氯消毒剂的杀菌性能。方法:采用悬液定量杀菌试验和现场消毒试验方法进行了实验研究。结果:含二氧化氯30 mg/L该消毒剂溶液对悬液内大肠杆菌作用5 min,杀灭对数值均大于5.0。含二氧化氯200 mg/L该消毒剂溶液对悬液内金黄色葡萄球菌作用10 min,杀灭对数值均大于5.0。用含200 mg/L二氧化氯消毒液擦拭消毒桌面,作用20 min,对物体表面自然菌的平均杀灭对数值为1.40。用含30 mg/L二氧化氯消毒液浸泡消毒黄瓜,作用10 min,对黄瓜上污染的大肠杆菌的杀灭对数值各样本均≥3.00。结论:该二氧化氯消毒剂对细菌繁殖体有较好的杀灭效果。
Objective:To know the germicidal property of monophyletic preparation of solid chlorine dioxide disinfectant.Methods:Suspention quantative germicidal test and field disinfection trial method were used to carry out experimental study.Results:The killing logarithm values of Escherichia coli in suspension exposed to the disinfectant solution containing chlorine dioxide 30 mg/L for 5 min were 5.0.The killing logarithm values of Staphylococcus aureus in suspension exposed to the disinfectant solution containing chlorine dioxide 200 mg/L for 10 min were 5.0.Wiping the table surface with the disinfection solution containing chlorine dioxide 200 mg/L for 20 min were 1.40.Immersion cucumber contaminated by artificial bacteria with the disinfection solution containing chlorine dioxide 30 mg/L for 10 min were ≥3.0.Conclusion:The chlorine dioxide disinfectant has good efficacy in killing vegetative forms of bacteria.
