Title: EXPERIMENTAL OBSERVATION ON GERMICIDAL PROPERTY OF IODOPHOR DISINFECTION SOLUTION
Abstract: In order to know the germicidal efficacy and related properties of iodophor disinfection solution,carrier 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.
