摘要
目的 观察脉冲电磁等离子体对细菌、真菌、芽孢、包膜病毒和无包膜病毒杀灭效果.方法 参照《消毒技术规范》(2002年版),评价脉冲电磁等离子体对细菌、真菌、芽孢、包膜病毒和无包膜病毒的杀灭效果.结果 脉冲电磁等离子体作用1.5 min,对金黄色葡萄球菌、大肠杆菌、白色念珠菌、枯草杆菌黑色变种芽孢的染菌载体杀灭对数值均＞3.00,对脊髓灰质炎病毒Ⅰ型(PV-Ⅰ)和人类冠状病毒HCoV-229E的杀灭对数值均＞4.00;产生的臭氧浓度低于《室内空气质量标准》(GB/T 18883-2022)对臭氧限量要求.结论 脉冲电磁等离子体对细菌、真菌、芽孢、包膜病毒和无包膜病毒的杀灭效果显著,具有快速、无残留、低成本等特点.
Abstract
Objective To investigate the killing effect of pulsed electromagnetic plasma on bacteria,fungi,spores,enveloped vi-ruses,and non-enveloped viruses.Methods The Technical Standard for Disinfection(2002 edition)was used to evaluate the killing effect of pulsed electromagnetic plasma on bacteria,fungi,spores,enveloped viruses,and non-enveloped viruses.Results After treatment for 1.5 minutes,pulsed electromagnetic plasma showed a log reduction value of＞3.00 against Staphylococcus aureus,Esche-richia coli,Candida albicans,and Bacillus subtilis var.niger spores and a log reduction value of＞4.00 for poliovirus Ⅰ(PV-Ⅰ)and hu-man coronavirus HCoV-229E.The concentration of ozone generated was below the limits for ozone in the Standards for Indoor Air Qual-ity(GB/T 18883-2022).Conclusion Pulsed electromagnetic plasma has a marked killing effect on bacteria,fungi,spores,enve-loped viruses,and non-enveloped viruses,with the characteristics of rapid action,residue-free outcomes,and low costs.
