Objective To develop Chlorine Dioxide Disinfection powder packed in single-ingredient that is more convenient for use and transportation. Methods Orthogonal experiment was adopt to improve disinfection powder. Stability test, suspension quantitative bactericidal test, simulation field trial and toxicity test were carried out according to Technical Standard for Disinfection, 2002 edition, Experimental Technical Standard, Ministry of Health, PRC. Results[WTBZ] The results of orthogonal experiment showed that the type of water had no effect on disinfection powder and the best ratio of natrium chlorite to citric acid was 1:3.10 gramme disinfection powder was fully dissolved in 20 milliliter water for 2 minutes, and then diluted by water to 500 milliliter; after 5 to 10 minutes, the concentration of chlorine dioxide could reach 272 mg/?L. After storing at 54 ℃ for 14 days, the average content of chlorine dioxide decreased by 5.03%.In suspension quantitative bactericidal test, the average killing logarithm value (KL) of Staphylococcus aureus and that of Escherichia coli exposed to solution containing 100 mg/?L chlorine dioxide for 2 minutes were over 5.00.In simulation field trial, the average KL of Escherichia coli exposed to solution containing 100mg/?L chlorine dioxide for 5 minutes was over 3.00. The disinfection powder was non-toxic, non-irritative for rabbit skin and had no function of inducing micronucleus of polychromatic erythrocytes of mouse marrow. Conclusions The solid chlorine dioxide disinfection powder packed in single-ingredient has bactericidal function.Such as environment friendly chemical clo2.
