摘要
目的观察柠檬桉叶油对室内空气消毒效果。方法采用熏蒸法和空气采样器方法进行了现场消毒效果评价,并与紫外线照射消毒法作平行比较。结果用纯柠檬桉叶油进行熏蒸消毒,柠檬桉叶油对室内空气中自然菌杀灭率达95.4%;在相同条件下用紫外线灯照射,对室内空气中自然菌杀灭率为89.7%。结论柠檬桉叶油熏蒸消毒,在10 ml/m3剂量下对室内空气中自然菌杀灭效果可达到消毒合格要求,比紫外线灯消毒效果好。
OBJECTIVE To observe the efficacy of lemon eucalyptus oil on disinfection of indoor air. METHODS Fumigating method and air sampling method were used to evaluate the disinfection efficacy. Ultraviolet disinfection method was used as control. RESULTS Aerosol spraying disinfection with the lemon eucalyptus oil at a dosage of 10 ml/m^3 followed by closing the room for 30 min can killed 95. 4% of the natural bacteria of indoor air. Irradiation by 30 W ultraviolet lamp for 30 min under same conditions killed 89. 7% of the natural bacteria of indoor air. CONCLUSIONS The efficacy of the lemon eucalyptus oil disinfectant at 10ml/m^3 concentration in killing natural bacteria in indoor air fulfils the requirement of eligible disinfection and is better than the disinfection efficacy of ultraviolet irradiation.
