EXAMINATION OF SPORICIDAL EFFICACY AND CORROSIVENESS OF SHUANG-LU DISINFECTANT LIQUID

Shuang-Lu Disinfectant Liquid is a compound disinfectant containing sodium hypochlorite and sodium chlorite Carrier quantitative bactericidal test indicated that the killing rate of spores of Bacillus subtilis var niger on cloth strip exposed to its solution containing 1000 mg/L available chlorine for 40 min at 18～22℃ attained 100%, while for the spores protected by 25% calf serum, such killing rate could be attained only after exposure for 80 min The available chlorine content of the disinfectant decreased by 9 85% after storing at 54℃ for 14 days Its solution containing 2000 mg/L available chlorine was slightly corrosive to copper, but essentially not corrosive to stainless steel, carbon steel and aluminum
