摘要
溴氯海因消净剂是以溴氯海因为主要杀菌成分,添加表面活性剂等成分配制而成的复方消毒剂。为了观察该消毒剂杀菌效果及稳定性,采用悬液定量杀菌试验进行了试验观察。结果,含有效溴氯550 mg/L的该消毒剂溶液作用15 m in,对大肠杆菌和金黄色葡萄球菌的平均杀灭对数值均≥5.00;有效溴氯含量为5500 mg/L,作用135m in,对枯草杆菌黑色变种芽孢的平均杀灭对数值为4.71;有效溴氯含量为550 mg/L,作用7.5 m in,对脊髓灰质炎病毒的平均灭活对数值≥4.00。该消毒剂于54℃存放14 d,有效溴氯下降率为3.54%。结论,溴氯海因消净剂在实验室能有效杀灭细菌繁殖体和细菌芽孢,储存性能稳定。
Bromochlorohydantoin Germicidal Detergent is compound disinfectant prepared from bromochlorohydantoin, the main germicidal ingredient, and other ingredients such as surfactant. In order to observe its germicidal efficacy and stability, suspension quantitative germicidal test was used to carry out experimental observation. Results： The average killing logarithm of Escherichia coli and Staphylococcus aureus exposed to the disinfectant solution containing available bromine and chlorine 550 mg/L for 15 min were ≥5.00, that of spores of Bacillus subtilis var. niger exposed to the solution containing available bromine and chlorine 5500 mg/L for 135 min was 4.71 and the average inactivating logarithm of poliovirus exposed to the solution containing available bromine and chlorine 550 mg/L for 7.5 min was ≥4.00. After the disinfectant was stored at 54℃ for 14 days, its available bromine and chlorine content decreased by 3.54%. Conclusions ： The Bromochlorohydantoin Germicidal Detergent can effectively kill the vegetative forms and spores of bacteria in laboratory. It is stable in storing.
