摘　　要：目的研究复方三氯异氰尿酸消毒剂的杀菌效果及其消毒相关性能。方法采用悬液定量杀菌试验和理化检测方法以及现场试验进行了试验观察。结果该复方三氯异氰尿酸泡腾片有效氯含量为质量分数49.47%,经54℃恒温存放14 d,有效氯含量下降率平均为1.96%。以含有效氯380 mg/L的复方三氯异氰尿酸泡腾片溶液作用5 min,对悬液内金黄色葡萄球菌和大肠杆菌平均杀灭对数值>5.00。能量试验证明,该消毒剂对大肠杆菌最低合格浓度为有效氯500 mg/L。用含有效氯380 mg/L该消毒泡腾片溶液喷洒物体表面至潮湿,作用10 min,对其表面上自然菌的平均杀灭对数值>1.00。结论该复方三氯异氰尿酸泡腾片性能稳定,对悬液内细菌繁殖体和物体表面自然菌都具有较强杀灭作用。Objective To study the germicidal efficacy and related disinfection properties of a compound trichloroisocyanuric acid disinfectant.Methods Suspension quantitative germicidal test and physicochemical examination method were used to carry out experimental observation.Results The available chlorine of the compound trichloroisocyanuric acid effervescent tablet was 49.47%（m/m） and decreased by 1.96% in average after storing at 54℃ for 14 days.The average killing logarithm values of Staphylococcus aureus and Escherichia coli in suspension exposed to the solution of the compound trichloroisocyanuric acid containing available chlorine 380 mg/L for 5 min were above 5.00.Capacity test showed that the minimal eligible concentration of the disinfectant for killing E.coli was of available chlorine 500 mg/L.Spraying the solution of the disinfectant containing available chlorine 380 mg/L on the object surface to moisten for 10 min,the average killing logarithm values of the natural bacteria on the surface was above 1.00.Conclusions The compound trichloroisocyanuric acid effervescent tablet is stable.It has high killing effect on vegetative forms of bacteria in suspension and natural bacteria on the object surface.
