摘要
氯溴海因属于有机溴氯类消毒剂,为了解其杀菌效果及消毒相关性能,采用悬液定量杀菌试验和理化分析方法进行了实验室观察。结果,以含有效氯溴400 mg/L的溴氯海因消毒液对大肠杆菌和金黄色葡萄球菌作用3m in,杀灭对数值>5.0,有效氯溴450 mg/L该液对白色念珠菌作用3 m in,杀灭对数值>4.0;以含有效氯溴3000mg/L的该消毒液作用30 m in,对枯草杆菌黑色变种芽孢杀灭对数值>5.0。用有效氯溴3000 mg/L该消毒液浸泡72 h,对不锈钢片基本无腐蚀、铜片轻度腐蚀、碳钢和铝片中度腐蚀。将该消毒剂原包装置于37℃储存3个月,有效氯溴下降率为6.33%。结论,有机氯溴消毒剂对细菌繁殖体和真菌以及细菌芽孢均具有很好的杀灭效果,性能稳定。
Chlorine bromine hydantoin belongs to organic bromine chlorine disinfectants. In order to know its germicidal efficacy and disinfection -related properties, suspension quantitative germicidal test and physicochemical analysis were used to carry out laboratory observation. Results： The killing logarithm of Escherichia coli and Staphylococcus aureus exposed to the bromine chlorine hydantoin disinfectant solution containing available chlorine bromine 400 mg/L for 3 min was 〉 5.0, that of Candida albicans exposed to the solution containing available chlorine bromine 450 mg/L for 3min was 〉 4.0 and that of Bacillus subtilis vat. niger spores exposed to the solution containing available chlorine bromine 3000 mg/L for 30 min was 〉 5.0. Immersion in the disinfectant solution containing available chlorine bromine 3000 mg/L for 72 h caused essentially no corrosion of stainless steel, slight corrosion of copper coupon and moderate corrosion of carbon steel and aluminum coupon. After the disinfectant in original packing was stored at 37℃ for 3 months, its available chlorine bromine content decreased by 6.33%. Conclusion ： organic chlorine bromine disinfectant has good efficacy in killing vegetative forms of bacteria, fungi and bacterial spores and its properties are stable.
