三效热原灭活剂杀菌效果与腐蚀性的试验观察

Germicidal Efficacy and Corrosiveness of San Xiao Pyrogeny Inactivator:An Experimental Observation

目的测定三效热原灭活剂的杀菌效果与腐蚀性。方法采用载体浸泡法测定三效热原灭活剂的杀菌效果。结果750 mg/L有效氯溶液对枯草芽胞杆菌黑色变种芽胞作用30 min,杀灭率达100%;500 mg/L有效氯溶液作用15 min,可将悬液中HBsAg抗原性破坏;杀菌作用因有机物存在而减弱;1000 mg/L有效氯溶液对不锈钢无腐蚀,对碳钢有中度腐蚀,对铜与铝有重度腐蚀。结论三效热原灭活剂是一种具有较好杀菌效果、使用安全的新型消毒剂。

OBJECTIVE To determine the germicidal efficacy and corrosiveness of San Xiao pyrogen inactivator. METHODS Its germicidal efficacy was measured with carrier test. RESULTS The killing rate of Bacillus subtilis var. niger spores exposed to its solution containing available chlorine 750mg/L for 30 rain attained 100%. Its solution containing available chlorine 5（10 mg/L with a 15 rain contact time could destroy HBsAg antigenicity in suspension. Its germicidal efficacy decreased in presence of organic substance. Its water solution containing available chlorine 1000mg/L was not corrosive to stainless steel, moderately corrosive to carbon steel and severely corrosive to copper and aluminum. CONCLUSIONS San Xiao pyrogen inactivator is a kind of original disinfectant which has better germicidal efficacy and uses safely.
