EXPERIMENTAL OBSERVATION ON GERMICIDAL EFFICACY AND STABILITY OF DISINFECTION EFFERVESCENT TABLET

In order to know the germicidal property and stability of the disinfection effervescent tablet, carrier quantitative germicidal test was used to carry out experimental observation. Results: The solution containing available chlorine 750 mg/L with a 40 min contact time killed 100% of spores of Bacillus subtilis var. niger, the solution containing available chlorine 400 mg/L with a 10 min contact time and 5 min contact time killed 100% of Candida albicans and Staphylococcus aureus respectively and the solution containing available chlorine 100 mg/L with a 10 min contact time killed 100% of Escherichia coli. The organic substance influenced slightly its germicidal efficacy. The available chlorine content of the effervescent tablet decreased by 7.30% after storing at 54℃ for 14 days. Conclusion: The disinfection effervescent tablet has good germicidal efficacy and stable property.
