摘　　要：目的:了解含氯复方消毒剂杀菌效果、稳定性及腐蚀性。方法:应用载体定量杀菌试验与金属腐蚀性试验。结果:以含有效氯2000mg/L的该消毒剂对布片上枯草杆菌黑色变种芽孢作用20min,含有效30mg/L的该溶液对布片上金黄色葡萄球菌和大肠杆菌作用10min和3min,含有效氯20mg/L的该溶液对白色念珠菌作用10min,杀灭率均为100%。含有效氯1500mg/L的该消毒剂溶液对不锈钢片上乙型肝炎表面抗原作用30min,可将其抗原性破坏。含有效氯2000ml/L的消毒剂溶液对不锈钢无腐蚀,对铝、铜有轻度腐蚀,对碳钢有中度腐蚀。结论:含氯复方消毒剂具有高效杀菌作用,对金属有腐蚀性。Objective： To know the germicidal efficacy and corrosiveness of compound chloring-containing disinfectant. Method： carrier quantitative germicidal test and metal corrosive test were carried out. Results： The killing rates of the follows were 100% ： spores of Bacillus subtilis var. niger on cloth strip exposed to the disinfectant solution containing available chlorine 2000 mg/ L for 20 min, Staphylococcus aureus and Escherichia coli on cloth strips exposed to the solution containing avaiable chlorine 30 mg/ L for 10 min and 3 min respectively and Candida albicans exposed to the solution containing avaiable chlorine 20 mg/1, for 10 min. The disinfectant solution containing available chlorine 1 500 mg/L, with a 30 min contact time could destroy the antigenicity of HBsAg on stainless steel coupon. The disinfectant solution containing available chlorine 2 000 mg/L was not corrosive to stainless steel, slightly corrosive to aluminum and copper and moderately corrosive to carbon steel. Conclusion： compound chloring- containing disinfectant has highly effective Germicidal action and is corrosive to metals.
