摘要
目的研究一种二氧化氯缓释剂(二元制剂)的消毒效果与稳定性。方法用理化分析和模拟现场试验方法进行观察。结果用丙二酸法测得该缓释剂的A液二氧化氯含量为4.1%,置37℃储存90d后,下降率为2.4%。将该缓释剂的B剂粉末倒入A液瓶子中,摇匀后置1m3密闭空间内,自然熏蒸1h、2h、4h和6h,对人工涂染的金黄色葡萄球菌杀灭率分别为64.3%、98.6%、100.0%和100.0%;放置第30d时,对人工涂染的金黄色葡萄球菌自然熏蒸1h、2h、4h和6h,其杀灭率分别为47.4%、65.0%、86.0%和93.1%。结论该二氧化氯缓释剂有良好的稳定性,在一定空间范围内有较好的杀菌效果。
Objctive To study the efficacy and stability of a disinfection agent with chlorine dioxide sustained release.Methods The agent was observed by physical and chemical analysis and simulated on-the-spot trial method.Results The chlorine dioxide content of A liquid was 4.1%,and the decreasing rate was 2.4% after 90 days in 37℃.When taking B powder to the A liquid bottle,shaking well and leading to an enclosed space,the killing rates were 64.3%,98.6%,100.0% and 100.0%for artificial paint Staphylococcus aureus when fumigation for 1h,2h,4hand 6h;and after 30 days,the killing rates were 47.4%,65.0%,86.0%and 93.1% when fumigation for 1h,2h,4hand 6h.Conclusion The chlorine dioxide sustained release agent exists good stability,and shows good germicidal efficacy in certain space scope.
