摘要
过氧丁二酸属过羧酸类化合物,为了解其杀菌效果及稳定性,采用载体定量杀菌试验对其进行了实验研究。结果,以含500 mg/L过氧丁二酸消毒液对布片上大肠杆菌和金黄色葡萄球菌作用2 m in,杀灭率均达99.99%。以含5000 mg/L过氧丁二酸的消毒液对白色念珠菌作用10 m in,对枯草杆菌黑色变种芽孢作用30 m in,杀灭率均达99.99%。该消毒液原液在37°C环境下放置3个月,过氧丁二酸含量平均下降率为1.5%。结论,过氧丁二酸具有较强的杀菌能力,性能稳定。
Persuccinic acid belongs to compounds of percarboxylic group. In order to know its germicidal efficacy and stability, carrier quantitative germicidal test was used to carry out experiment study on it. Results ： Lti - An - Kang disinfection solution containing persuccinic acid 500 mg/L with a 2 min contact time killed 99.99% of both Escherichia coli and Staphylococcus aureus on cloth strips. The disinfection solution containing persuccinic acid 5000 mg/L with a 10 min contact time and 30 min contact time killed 99.99% of Candida albicans and spores of Bacillus subtilis var. niger respectively. After the stock solution of the disinfection solution was stored at 37℃ for 3 months, its persuccinic acid content decreased by 1.5% in average. Conclusion： Persuccinic acid has relatively strong germicidal efficacy and is stable in property.
