摘要
高氧化还原电位酸性水(EOW)是电解加有食盐蒸馏水时,在阳极产生氧化还原电位(ORP)≥1040 mV, pH值≤3.69,含有效氯<80mg/ L的水。经检测,水中食盐含量为 550~ 950 mg/ L时,电解 10 min,该水 ORP随食盐含量增加而升高;电解 8~ 12 min, ORP随电解时间延长而升高。悬液定量杀菌试验表明,在 20℃下, ORP为 1152 mV的该水,对不含蛋白胨悬液中枯草杆菌黑色变种芽胞作用40 min,杀灭率达100%。杀菌效果随ORP升高、温度上升而增强,因蛋白胨存在而减弱。
Acidic water (electrolyzed oxidizing water, EOW) with high redox potential is the water with redox potential (ORP) ≥ 1040 mV, pH value ≤3.69 and containing available chlorine < 80mg / L, which are produced at the anode during electrolysis of distilled water containing table salt. Examination found that when the table salt content of water was 550-950 mg / L and electrolysis was carried out for 10 min, the ORP of water increased with increasing table salt content. When the eletrolysis time was 8-12 min, the ORP increased with prolonging electrolysis time. The suspension quantitative germicidal test indicated that at 20℃, the killing rate of Bacillus subtilis var. niger spores in suspension without peptone exposed to the water with ORP of 1152 mV attained 100%. The germicidal efficacy increased with increasing ORP and temperature and decreased in presence of peptone.
