Observation on germicidal property of monophyletic preparation of solid chlorine dioxide disinfectant

Objective:To know the germicidal property of monophyletic preparation of solid chlorine dioxide disinfectant.Methods:Suspention quantative germicidal test and field disinfection trial method were used to carry out experimental study.Results:The killing logarithm values of Escherichia coli in suspension exposed to the disinfectant solution containing chlorine dioxide 30 mg/L for 5 min were 5.0.The killing logarithm values of Staphylococcus aureus in suspension exposed to the disinfectant solution containing chlorine dioxide 200 mg/L for 10 min were 5.0.Wiping the table surface with the disinfection solution containing chlorine dioxide 200 mg/L for 20 min were 1.40.Immersion cucumber contaminated by artificial bacteria with the disinfection solution containing chlorine dioxide 30 mg/L for 10 min were ≥3.0.Conclusion:The chlorine dioxide disinfectant has good efficacy in killing vegetative forms of bacteria.
