摘　　要：目的研究气体二氧化氯制备技术及其在消毒中的应用。方法通过化学反应方式制备二氧化氯气体和气体熏蒸载体方法,对二氧化氯气体制备技术及其杀菌效果进行评价。结果亚氯酸钠、硫酸氢钠和抗坏血酸钠以科学配比混合发生二氧化氯气体。在常温条件下于生物安全柜内,用浓度为6 000 mg/m^(3)的气体二氧化氯,作用30 min可完全杀灭载体上枯草杆菌黑色变种芽孢。结论本研究确定了气体二氧化氯发生的新配比,气体熏蒸可有效杀灭载体上枯草杆菌黑色变种芽孢。Objective To study the rapid preparation of chlorine dioxide gas and its application in disinfection.Methods Chlorine dioxide gas was generated by chemical reaction,and carrier quantitative fumigation test was used to evaluate the germicidal effect.Results Sodium chlorite,sodium bisulfate,sodium ascorbate are mixed in scientific ratio to get chlorine dioxide gas.Under room temperature,spores of Bacillus subtilis var niger on the carrier in the biosafety cabinet could be completely killed in 30 min by chlorine dioxide gas maintained at 6 000 mg/m^(3).Conclusion In this study,we determine the new ratio of chlorine dioxide gas generation,and spores of Bacillus subtilis var niger on the carrier can be completely killed by chlorine dioxide fumigation.
