目的观察一种以次氯酸为有效成分的消毒液的杀菌效果。方法用悬液定量杀菌试验方法对该消毒液进行了实验室杀菌效果观察。结果用有效氯浓度为100 mg/L的该消毒液作用5 min,对悬液内沙门菌、志贺菌、单增李斯特杆菌、绿脓杆菌、肠出血性大肠杆菌(O157∶H7)和耐热大肠菌群的平均杀灭对数值均大于5.00。结论这种含氯消毒液对试验所用6种细菌具有良好的杀菌效果。
Objective To observe the bactericidal effect of a disinfectant solution containing hypochlorous acid as an active ingredient. Methods The bactericidal effect of the disinfectant was observed with the method of quantitative disinfection of suspension. Results With the disinfectant with available chlorine concentration of 100 mg / L for 5 min, the effects of Salmonella, Shigella, Listeria monocytogenes, Pseudomonas aeruginosa, enterohemorrhagic Escherichia coli (O157: H7) and Average heat-killed coliform kill logarithm values were greater than 5.00. Conclusion The chlorine-containing disinfectant has good bactericidal effect on the 6 bacteria used in the experiment.
