高氧化还原电位酸性水杀灭微生物效果及其稳定性的试验观察

EXPERIMENTAL OBSERVATION ON GERMICIDAL EFFICACY AND STABILITY OF ACIDIC WATER WITH HIGH REDOX POTENTIAL

高氧化还原电位酸性水的氧化还原电位＞１１００ｍＶ，ｐＨ值＜２７。经检测，该水对无有机物保护的细菌繁殖体与白色念珠菌作用１～５ｍｉｎ，对枯草杆菌黑色变种芽胞作用２０ｍｉｎ，杀灭率均为１００％。用于擦拭工作台面或浸泡阴道窥器１～２ｍｉｎ，对自然菌的灭除率分别为８７９２％与７４８０％～８０４９％。放置室温下３ｄ，该水氧化还原电位明显下降，但ｐＨ值无明显变化。

The acidic water with high redox potential has a redox potential of >1100 mV and a pH of <2 7 Germicidal test found that the water could kill 100% of bacterial vegetative forms unprotected by organic substance and Candida albicans in 1～5 min and 100% of spores of Bacillus subtilis var niger in 20 min When it was used for wiping the surface of working table or immersing the vaginoscope for 1～2 min, the killing rate of natural bacteria on these articles was 87 92% and 74 80%～80 49% respectively After it was kept at room temperature for 3 days, its redox potential decreased obviously, but the pH value did not change significantly
