环境物体表面污染被认为是感染的一个来源,做好医院物体表面的消毒一直是医院感染综合预防控制的措施之一[1]。传统的化学消毒剂在杀灭致病微生物的同时,往往也带来对工作人员的职业危害以及对环境的破坏,如对城市地下水的化学污染就是突出问题之一。因此,应该倡导绿色环保消毒剂,尤其是那些最终会降解为无害成分的消毒剂[2]。微酸性电解水(SlAEW)于20世纪90年代末在日本首先研发[3],是在强酸性 Contamination of environmental objects is considered as a source of infection, and good disinfection of the surface of hospital objects has been one of the measures of comprehensive prevention and control of nosocomial infections [1]. Traditional chemical disinfectants often cause occupational hazards to workers and environmental damage while killing pathogenic microorganisms. One of the prominent problems is the chemical pollution of urban groundwater. Therefore, green disinfectants should be advocated, especially those that will eventually degrade into harmless ingredients [2]. Slightly acidic electrolyzed water (SlAEW) was first developed in Japan in the late 1990s [3] and is strongly acidic
