过氧化物复合消毒剂的制备及其杀菌效果的评价

过氧化物复合消毒剂是由一种电解装置生产合成,采用定量杀菌试验和动物试验,对其消毒效果及毒性进行了试验观察。结果,含过氧化氢600mg/L的过氧化物复合消毒剂,作用5min和10min,对大肠杆菌和金黄色葡萄球菌平均杀灭率均达到99.9%以上。含过氧化氢2200mg/L的该消毒剂,作用10min,对模拟现场物体表面枯草杆菌黑色变种芽孢平均消除率为99.93%。有机物对该消毒剂杀菌效果无明显影响;将其储存于54℃14d,过氧化氢含量下降率为9.93%。该消毒剂属于实际无毒,弱蓄积毒性,对动物皮肤无明显刺激性。结论,过氧化物复合消毒剂具有良好的杀菌效果,储存性能稳定,毒性低,刺激性小。

PREPARATION OF COMPOUND DISINFECTANT OF PEROXIDE AND EVALUATION OF ITS GERMICIDAL EFFICACY

The compound disinfectant of peroxide was synthesized and produced by an electrolysis device. Quantitative germicidal test and animal test were used to observe experimentally its disinfection efficacy and toxicity. Results: The average killing rates of Escherichia coli and Staphylococcus aureus exposed to the compound disinfectant of peroxide containing hydrogen peroxide 600 mg/L for 5 min and 10 min respectively attained over 99.9%. The average eradicating rate of spores of Bacillus subtilis var. niger on simulated on-the-spot object surface exposed to the disinfectant containing hydrogen peroxide 2200 mg/L for 10 min was 99.93%. Organic substance had no significant influence on the germicidal efficacy of the disinfectant. After storing at 54℃ for 14 days, its hydrogen peroxide content decreased by 9.93%. This disinfectant belongs to practically nontoxic substance with weak cumulative toxicity and has no obvious irritating effect on animal skin. Conclusion: The compound disinfectant of peroxide has good germicidal efficacy, low toxicity and low irritating effect and is stable on storing.
