高氧化还原电位酸性水部份性能的试验观察

EXPERIMENTAL OBSERVATION ON SOME PROPERTIES OF ELECTROLYZED OXIDIZING WATER WITH HIGH REDOX POTENTIAL

对氧化还原电位为１１５３～１１６５ｍＶ、ｐＨ２．２１～２．２７，含有效氯５０．２９～５８．２４ｍｇ／Ｌ的高氧化还原电位酸性水（简称ＥＯＷ），进行载体浸泡定量杀菌效果检测及稳定性、腐蚀性测定。结果，ＥＯＷ原液对布片上白色念珠菌作用３ｍｉｎ，杀灭率达９９．９１％，作用２０ｍｉｎ的杀灭率为１００％。小牛血清的存在，对其杀菌作用有一定影响。该液装于不透明塑料瓶中，置于 ５４℃温箱内存放 １４ ｄ， ＯＲＰ值下降到 １１４７～１１５０ｍＶ，ｐＨ升至２．３５～２．４２。该液对不锈钢无腐蚀作用，对铜有轻度腐蚀作用，对碳钢和铝有中度腐蚀作用。

Carrier immersion quantitative germicidal efficacy test and examination of stability and corrosiveness of electrolyzed oxidizing water (EOW for short) with redox Potential (ORP) of 1153～1165 mV, pH 2.21 ～ 2.27 and available chlorine content of 50.29～58.24 mg / L were carried out. The results showed that the killing rate of Candida albicans on cloth strip exposed to EOW stock solution for 3 min and 20 min was 99.91 % and 100% respectively. Presence of calf serum had certain influence on its germicidal efficacy. After storing this solution contained in opaque plastic bottle in 54℃ incubator for 14 days, its ORP value decreased to 1147 ～ 1150 mV and its PH value increased to 2.35～ 2.42. The EOW had no corrosive effect on stainless steel, slightly corrosive effect on copper and moderately corrosive effect on carbon steel and aluminum.
