OBSERVATION ON PERFORMANCE OF HONG-SHENG DISINFECTION SOLUTION GENERATOR AND THE GERMICIDAL EFFICACY OF THE DISINFECTANT SOLUTION

In order to know the performance of Hong-Sheng disinfectection solution generator and the germicidal efficacy of the disinfection solution, the available chlorine content in the disinfection solution produced by the generator under different conditions was measured and carrier quantitative germicidal test was carried out. Results: With prolonging the working time and increasing the table salt concentration, the available chlorine content increased gradually. The killing rates of Staphylococcus aureus and Escherichia coli on cloth strips exposed to the disinfection solution containing available chlorine 100 mg/L for 5 min and Candida albicans exposed to the solution containing available chlorine 200 mg/L for 5 min were over 99.90%. The disinfection solution containing available chlorine 1000 mg/L with a 60 min contact time could kill 100% of spores of Bacillus subtilis var. niger.
