摘　　要：为了解二溴海因消毒粉剂的杀菌效果,以悬液定量杀菌试验方法对其进行了试验观察。结果,含有效溴400mg/L的该消毒粉剂溶液作用10 m in,对大肠杆菌、金黄色葡萄球菌的杀灭对数值分别为6.37和5.19。含有效溴3000 mg/L的该粉剂溶液作用6 h,对枯草杆菌黑色变种芽孢的杀灭对数值为3.10。用含有效溴400 mg/L的该粉剂溶液浸泡作用10 m in,对人工染于餐具上的大肠杆菌杀灭率达99.99%。有机干扰物存在时对二溴海因消毒粉剂杀菌效果有影响。用含有效溴1000 mg/L的二溴海因溶液浸泡72 h,对不锈钢基本无腐蚀,对铜、铝有轻度腐蚀,对碳钢有中度腐蚀。结论,二溴海因消毒粉剂可有效杀灭细菌繁殖体和细菌芽孢,该消毒剂溶液对金属具有腐蚀性。In order to know the germicidal efficacy of dibromohydantoin disinfection powder, suspension quantitative germicidal test was used to carry out experimental observation. Results： The reduction in viability of Escherichia coli and Staphylococcus aureus exposed to the disinfection powder solution containing available bromine 400 mg/L for 10 min were 10^6.37 and 10^5.19 respectively. The reduction in viability of spores ofBaciUus subtilis var. niger exposed to the disinfection powder solution containing available bromine 3000 mg/L for 6 h was 10^3.10 Immersion in the disinfection powder solution containing available bromine 400 mg/L for 10 min killed 99.99% of the Escherichia coli artificially contaminating the tableware. Presence of organic interfering substance had influence on the germicidal efficacy of dibromohydantoin disinfection powder. Immersion in dibromohydantoin solution containing available bromine 1000 mg/L for 72 h caused essentially no corrosion of stainless steel, slight corrosion of copper and aluminum and moderate corrosion of carbon steel. Conclusions： Dibromohydantoin disinfection powder can effectively kill vegetative forms of bacteria and bacterial spores. Its solution is corrosive to metals.
