摘　　要：目的了解过氧化氢银离子复方消毒剂消毒相关性能。方法采用载体定性灭菌试验法,对该过氧化氢银离子复方消毒剂杀菌效果及稳定性进行了观察。结果以含100 g/L过氧化氢与109 mg/L的银离子复方消毒剂,对载体上枯草杆菌黑色变种芽孢作用90 min,或对污染在止血钳齿端上的枯草杆菌黑色变种芽孢作用90 min,均可达到完全杀灭。将该复方消毒剂原液密封保存于37℃恒温箱中3个月,其过氧化氢及银离子含量平均下降率分别为4.98%和3.43%。结论过氧化氢银离子复方消毒剂对细菌芽孢均具有较强的杀灭效果,性能稳定。Objective To study the disinfection properties of hydrogen peroxide silver ion disinfectant. Methods Carrier qualitative germicidal tests were used to observe the germicidal efficacy and stability of hydrogen peroxide silver ion disinfectant. Results The disinfectant containing 100 g/L hydrogen peroxide and 109 mg/L silver ion with a 90 min contact time could kill completely the spores of Bacillus subtilis var. niger on the carrier and also on contaminated teeth of hemostatic forceps. After the stock solution of the disinfectant in airtight packing was stored at 37℃ for 3 months, its hydrogen peroxide content and silver ion content decreased by 4.98% and 3.43% in average, respectively. Conclusion Hydrogen peroxide silver ion disinfectant has relatively strong killing effect on the bacterial spores. Its properties are stable.
