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 understand the disinfection performance of hydrogen peroxide silver ion disinfectant. Methods The method of qualitative sterilization was used to observe the bactericidal effect and stability of the compound disinfectant of hydrogen peroxide. Results The Bacillus subtilis black spores were spiked with 100 g / L hydrogen peroxide and 109 mg / L silver ion for 90 min, or the Bacillus subtilis sp. 90 min, can achieve complete kill. The compound disinfectant stock solution sealed in 37 ℃ incubator for 3 months, the average hydrogen peroxide and silver ion content decreased 4.98% and 3.43%, respectively. Conclusion Hydrogen peroxide silver ion disinfectant has strong killing effect on bacterial spores and has stable performance.
