摘要
为了解碘伏消毒液杀菌效果及相关性能,采用载体定量杀菌试验方法进行了实验室观察和现场考核。结果,以含25 mg/L有效碘的碘伏消毒液对金黄色葡萄球菌和大肠杆菌作用10 m in,杀灭率为100%;用100 mg/L有效碘的该消毒液对白色念株菌作用10 m in,杀灭率为100%。用碘伏消毒液原液对志愿者手进行擦拭消毒作用3m in,可使手上自然菌平均减少率为97.61%。碘伏消毒液在37℃存放3个月,有效碘含量下降率为7.75%。经碘伏消毒液浸泡72 h,对不锈钢基本无腐蚀,对铝中度腐蚀,对碳钢和铜有重度腐蚀。结论,碘伏消毒液对细菌繁殖体和真菌都具有很强的杀灭效果,储存稳定,但腐蚀性明显。
In order to know the germicidal efficacy and related properties of iodophor disinfection solution, cartier quantitative germicidal test was used to carry out laboratory observation and field trial. Results ： The iodophor disinfection solution containing available iodine 25 mg/L with a 10 min contact time killed 100% of Staphylococcus aureus and Escherichia coli and the disinfection solution containing available iodine 100 mg/L with a 10 min contact time killed also 100% of Candida albicans. Wiping disinfection of volunteers＇ hands with stock solution of iodophor disinfection solution for 3 min could reduce the natural bacteria on hands by 97.61% in average. After the iodophor disinfection solution was stored at 37℃ for 3 months, its available iodine content decreased by 7.75%. Immersion in iodophor disinfection solution for 72 h caused no corrosion of stainless steel, moderate corrosion of aluminum and heavy corrosion of carbon steel and copper. Conclusions ： Iodophor disinfection solution has high efficacy in killing vegetative forms of bacteria and fungi. It is stable in storing, but has significant corrosiveness.
