摘　　要：目的观察不同制剂稳定性二氧化氯消毒液杀菌效果。方法采用悬液定量杀菌方法,对不同活化剂配制的二氧化氯消毒液杀菌效果进行了实验室检测。结果采用柠檬酸和盐酸作为活化剂,以亚氯酸钠作为二氧化氯原液,将二者同时投入到不同倍数水中进行活化。随着原液稀释倍数的增加,经柠檬酸和盐酸活化的二氧化氯对金黄色葡萄球菌、白色念珠菌和枯草杆菌黑色变种芽孢的杀灭效果均呈下降趋势。结论将活化剂与亚氯酸钠同时投入到水中,随着水量的递增,其杀菌效果下降;不能将活化与稀释两个过程同步进行,必须先活化后再稀释。Objective To observe the germicidal efficacy of chlorine dioxide obtained by different preparation process.Methods The germicidal efficacy of chlorine dioxide obtained by different activation was evaluated by suspension quantitative germicidal test.Results Chlorine dioxide was activate by adding citric acid and hydrochloric acid as the activater into sodium chlorite as original solution with different multiple water.The killing rate of Staphylococcus aureus,Candida albicans and spores of Bacillus subtilis var.niger declined by increasing the diluted multiple.Conclusions The germicidal efficacy of chlorine dioxide declined with increasing water by adding both activation and sodium chlorite into water in the same time.The activation and dilution can＇t be operated at the same time.The proper procedure was to activate the stabilized chlorine dioxide then dilute to the concentration you want.
