摘　　要：目的观察一种次氯酸钠发生器产生的消毒液的杀菌效果,为实际应用提供依据。方法采用悬液定量杀菌法,对其杀菌性能进行观察。结果该次氯酸钠发生器在设定条件下,可生产出含有效氯约3 895 mg/L的次氯酸钠消毒液。用含有效氯600 mg/L该次氯酸钠消毒液作用15 min,对悬液内金黄色葡萄球菌的杀灭对数值>5.00;含有效氯350 mg/L的该消毒液作用15 min,对悬液内大肠杆菌的杀灭对数值>5.00;同样条件下杀灭白色念珠菌对数值达到4.0,则需要含有效氯300 mg/L。结论该次氯酸钠发生器产生的次氯酸钠消毒液对细菌繁殖体及真菌有良好的杀菌效果。Objective To observe the germicidal efficacy of a sodium hypochlorite generator, and provide the basis for practical application. Methods Suspension quantitative germicidal test was used to carry out the germicidal efficacy ob- servation. Results The sodium hypochlorite generator can produce 3 895 mg/L available chlorine in the setting condi- tions. The killing logarithm values of Staphylococcus aureus exposed to the solution containing available chlorine 600 mg/L for 15 min, Escherichia coli exposed to the solution containing available chlorine 350 mg/L for 15 min were all above 5.00. The killing logarithm values of Candida albicans exposed to the solution containing available chlorine 300 mg/L for 15 min was above 4.00. Conclusion The sodium hypochlorite generator has good germicidal efficacy to the vegetative bacteria and fugis .
