摘　　要：目的为了了解防冻剂对二氧化氯杀菌效果的影响。方法采用悬液定量杀菌试验进行了实验室研究。结果乙醇、氯化钠均可作为二氧化氯低温消毒防冻剂。以体积分数为10%的乙醇为防冻剂的二氧化氯消毒液,在-20℃条件下,用含有效氯100mg/L,250mg/L的二氧化氯消毒液作用20min,对枯草杆菌黑色变种芽孢的杀灭率分别为100.00%、99.97%。结论低温条件下,在二氧化氯消毒液中加入乙醇或氯化钠做为防冻剂,具增效、协同作用,能有效杀灭枯草杆菌黑色变种芽孢。Objective Study the impact of antifreeze on chlorine dioxide^s disinfection efficacy.Methods Observe the killing efficacy by suspension quantitative germicidal test in laboratory. Results Both Ethanol and sodium chloride can be used as chlorine dioxide＇s low-temperature antifreezes. Killing efficacy of spores of Bacillus subtilis var. niger reach 100.00% and 99.97% respectively by using chlorine dioxide disinfectant containing 100mg/L, 250mg/L with 20 min contact time under -20℃ temperature. Conclusion The chlorine dioxide disinfectant has good and even enhanced efficacy and synergetic efficacy in killing spores of Bacillus subtilis var. niger after adding antifreeze as ethanol or sodium chloride under low temperature.
