提要 三效热原灭活剂为含二氯异氰尿酸钠、去污剂等成分的含氯复方消毒剂,原粉含有效氯不低于8.0%。对其水溶液杀灭微生物效果及腐蚀性进行了试验观察。以其含有效氯300 mg/L的溶液对悬液中大肠杆菌与金黄色葡萄球菌分别作用1 min与5 min,以含有效氯750 mg/L该液对枯草杆菌黑色变种芽胞作用30 min,杀灭率均达100%;以含有效氯500 mg/L该液作用15 min,可将悬液中HBsAg抗原性破坏。以含有效氯400 mg/L该液浸泡污染有细菌内毒素玻璃小管45 min,可使其热原全部转阴性。杀菌作用因有机物存在而减弱。该剂含有效氯1 000 mg/L的水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。其粉剂装于塑料瓶中,54℃下存放14 d,有效氯含量平均下降率为9.28%。 关键词 含氯复方消毒剂 二氯异氰尿酸钠 杀芽胞剂 枯草杆菌黑色变种 大肠杆菌 金黄色葡萄球菌 HBsAg 细菌内毒素 稳定性 腐蚀性

Abstract
San Xiao Pyrogen Inactivator is chlorine-containing compound disinfectant conatining sodium dichloroisocyanurate, detergent and other ingredients. The original powder contains not less than 8.0% of available chlorine. The germicidal efficacy and corrosiveness of its water solution were observed experimentally. The killing rate of Escherichia coli and Staphylococcus aureus in suspension exposed to its solution containing available chlorine 300 mg/L for 1 min and 5 min respectively and spores of Bacillus subtilis var. niger exposed to its solution containing available chlorine 750 mg/L for 30 min attained 100%. Its solution containing available chlorine 500 mg/L with a 15 min contact time could destroy HBsAg antigenicity in suspension. Immersion of small glass tube contaminated by bacterial endotoxin in its solution containing available chlorine 400 mg/L for 45 min could cause full negative coversion of pyrogen. Its germicidal efficacy decreased in presence of organic substance. Its water solution containing available chlorine 1000 mg/L was not corrosive to stainless steel, moderately corrosive to carbon steel and severely corrosive to copper and aluminum. The available chlorine content of its powder packed in plastic bottle decreased by 9.28% in average aft[1] [2] 下一页 上一个医学论文: 二氧化氯溶液杀灭微生物效果与腐蚀性试验观察 下一个医学论文: JL消毒剂杀灭微生物效果与腐蚀性的试验观察
