摘　　要：目的研究一种二氧化氯消毒剂的消毒相关性能。方法采用悬液定量杀菌试验和现场消毒试验,对该消毒剂进行了试验观察。结果用含二氧化氯121 mg/L该消毒剂水溶液作用5 min,对悬液内大肠杆菌和金黄色葡萄球菌的平均杀灭对数值均>5.00。对大肠杆菌的能量试验,其最低合格浓度为600 mg/L二氧化氯。用含二氧化氯121 mg/L消毒液喷洒木质物体表面至其潮湿,作用20 min,对其表面上的自然菌平均杀灭对数值>1.00;浸泡织物10 min,对其携带的自然菌平均杀灭对数值>1.00。结论该消毒剂对细菌繁殖体和物体表面自然菌均具有较强的杀灭作用。Objective To study the antiseptic property of a chlorine dioxide disinfectant.Methods Suspension quantitative germicidal test and field disinfection test are used to observe the disinfectant properties in laboratory.Results The average killing logarithm value of Escherichia coli and Staphylococcus aureus in suspension are above 5.00 by the disinfectant water solution containing 121 mg / L chlorine dioxide for 5 minutes.In the energy test of Escherichia coli,the lowest certified concentration is 600 mg / L chlorine dioxide.The disinfectant water solution containing 121 mg / L chlorine dioxide is used to spray wood surface until the surface is moist for 20 minutes,and the average killing logarithmic values of natural bacterium on the surface is above 1.00.If the disinfectant water solution containing 121 mg / L chlorine dioxide is used to soak fabrics for 10 minutes,and the average killing logarithmic values of the natural bacterium carried in the fabrics is above 1.00.Conclusion The disinfectant has relatively strong disinfection effect to bacterial vegetative form and natural bacteria on body surface.
