摘　　要：为了解复方含氯泡腾消毒片的消毒相关性能,采用悬液定量杀菌试验和理化检验方法进行实验室和现场试验观察。结果,以含有效氯300 mg/L的该消毒片水溶液对金黄色葡萄球菌作用10 m in,杀灭对数值>5.00;有效氯400 mg/L,对大肠杆菌作用5 m in,杀灭对数值>5.00。用有效氯2000 mg/L该消毒片水溶液作用30 m in,对枯草杆菌黑色变种芽孢杀灭对数值>5.00。对大肠杆菌进行能量试验,最低合格浓度为有效氯800 mg/L。在模拟现场消毒试验中,以有效氯400 mg/L水溶液作擦拭消毒并作用10 m in,对物体表面上细菌繁殖体杀灭对数值>3.0;有效氯2000 mg/L水溶液浸泡处理医疗器械60 m in,对污染在器械上枯草杆菌黑色变种芽孢杀灭对数值亦>3.0。含有效氯2000 mg/L的消毒液浸泡72h对金属有不同程度腐蚀性。结论,含氯复方消毒片具有良好的杀菌效果,但对金属有一定腐蚀性。In order to know the disinfection - related properties compound chlorine - containing effervescent disinfection tablet, suspension quantitative germicidal test and physicochemical examination method were used to carry out laboratory and field trial observation. Results： The killing logarithm values of Staphylococcus aureus exposed to the water solution of the disinfection tablet containing available chlorine 300 mg/L for 10 min, Escherichia coli exposed to the disinfection tablet solution containing available chlorine 400 mg/L for 5 min and Bacillus subtilis var. niger spores exposed to the disinfection tablet solution containing available chlorine 2000 mg/L for 30 min were 〉 5.00. In capacity test for E. coli , the minimal eligible concentration was available chlorine 800 mg/L. In simulated field disinfection trial, wiping disinfection with the disinfection tablet water solution containing available chlorine 400 mg/L for 10 min killed vegetative forms of bacteria on surfaces by a logarithm 〉 3.0. Immersion of medical instruments in its water solution containing available chlorine 2000 mg/L for 60 min killed B. subtilis var. niger spores on the instruments by a logarithm 〉 3.0. Immersion in the disinfection tablet solution containing available chlorine 20000 mg/L for 72 h caused corrosion of metals to various degrees. Conclusion ： Compound chlorine -containing disinfection tablet has good germicidal efficacy, but it causes corrosion of metals to certain degree.
