摘　　要：目的观察一种二氧化氯消毒粉的杀菌性能。方法用悬液定量杀菌试验和理化测定方法,对该消毒剂性能进行了实验室试验。结果消毒粉A和B两剂混合,溶解于2 L蒸馏水中活化后二氧化氯含量为3 902 mg/L。用浓度为78 mg/L二氧化氯溶液作用5 min,对悬液内金黄色葡萄球菌和大肠杆菌平均杀灭对数值均>5.00。用相同浓度该二氧化氯消毒液对物体表面作擦拭消毒并作用10min,对表面自然菌平均杀灭对数值>1.00。在天然水样中加入该二氧化氯约1.0 mg/L作用30 min,使水样中大肠杆菌下降至0 cfu/100 ml。结论该二氧化氯消毒粉杀菌效果较好,在较低浓度条件下对物体表面和水体消毒均效果较好。Objective To evaluate the germicidal efficacy of a chlorine dioxide disinfectant powder.Methods Suspension quantitative germicidal test and physicochemical examination were used to evaluate the disinfectant property in laboratory.Results Powder A and B were compounded,and then were solved in 2 L distilled water for inactivation.The concentration of chlorine dioxide was 3 902 mg/L after inactivation for 20 min.The average killing logarithm value of Staphylococcus aureus and Escherichia coli in the suspension exposed to the disinfection solution with the concentration of chlorine dioxide was 78 mg/L for 5 min were both 5.00.And the average killing logarithm value of natural bacteria on material surface was 1.0 when scripted with 78 mg/L chlorine dioxide for 10 min.1.0 mg/L chlorine dioxide can reduce Escherichia coli added into natural water to 0 cfu /100ml in 30 min.Conclusion The chlorine dioxide disinfectant powder has good germicidal efficacy.It can be used for material surface and water disinfection.
