摘要
目的 观察一种次溴酸发生装置产生的消毒液的杀菌效果,探索其应用的可行性.方法 采用理化分析方法和悬液定量杀菌试验,对该含溴消毒液的理化性能和杀菌效果进行实验室观察.结果 在设定条件下,发生装置可生产出含有效溴约1 300 mg/L的消毒液.用含有效溴100 mg/L的该消毒液作用5 min,对悬液内大肠埃希菌、金黄色葡萄球菌的杀灭对数值均>5.00;用含有效溴200 mg/L该消毒液作用2 min,对铜绿假单胞菌的平均杀灭对数值>5.00,对白念珠菌的平均杀灭对数值>4.00;用含有效溴500 mg/L该消毒液作用15 min,对枯草杆菌黑色变种芽孢的平均杀灭对数值>5.00;用含有效溴500 mg/L该消毒液作用10 min,对脊髓灰质炎病毒的平均杀灭对数值>4.00.有效溴含量500 mg/L该消毒液浸泡金属片72 h后,对不锈钢、铜、铝轻度腐蚀,对碳钢中度腐蚀.结论 该消毒液对细菌繁殖体、真菌、细菌芽孢和脊髓灰质炎病毒有良好的杀灭效果.
Abstract
Objective To observe the germicidal efficacy of the disinfectant produced by a hypobromous acid generator and to explore the feasibility of its application.Methods Physicochemical analysis method and suspension quantitative germicidal test were used to observe the properties and germicidal efficacy of the bromine-containing disinfectant.Results Under the set conditions,the generator could produce disinfectant containing about 1 300 mg/L of available bromine.Staphylococcus aureus and Escherichia coli in suspension were exposed to the disinfectant containing 100 mg/L of available bromine for 5 min,and the killing log values were all>5.00;Pseudomonas aeruginosa and Candida albicans were exposed to the disinfectant containing 200 mg/L of available bromine for 5 min,and the average killing log value of Pseudomonas aeruginosa was>5.00 and the average killing log value of Candida albicans was>4.00;The spores of Bacillus subtilis var niger were treated with the disinfectant containing 500 mg/L of available bromine for 15 min,and the average killing log value was>5.00.The polioviruses were treated with the disinfectant containing 500 mg/L of available bromine for 10 min,and the average killing log value was>4.00.The metal pieces were soaked in the disinfectant containing 500 mg/L of available bromine for 72 h,there was slight corrosion for stainless steel,copper and aluminum,and moderate corrosion for carbon steel.Conclusion The disinfectant has good germicidal efficacy to the bacterial propagules,fungi,bacterial spores and poliovirus.
