摘　　要：本文对酸性氧化电位水(EOW)的制备进行了考察。结果表明:分别用铂、钯做阴极涂层时性能相近;阳离子交换膜的性能要优于阴离子交换膜。在NaCl的浓度为0.060%,电解电流为400A/m2,酸性水流量均为2L/min情况下,得到的酸性氧化电位水,其pH值为2.37,ORP值为1149mV,有效氯值为74.9 mg/L。另外,本文还对NaCl浓度和电流密度对EOW性能的影响进行了考察,表明NaCl浓度、电流密度越大,得到EOW性能越好。The electrolyzet-oxiding water was prepared. It is showed through the investigation of the cathodic coating that the preparation performance with platinum cathodic coating approaches to that with palladium cathodic coating; the investigation showed that the performance of cation exchage membrane was superior to that of anion exchange membrane. Under the conditions of 0.060% NaCl concentration, electrolytic current of 400A/m^2, acidic water flow of 2L/min., the electrolyzed-oxiding water obtained had pH value of 2.37, ORP value of 1149mV and effective chlorine value of 74.9mg/L. In addition, it is a showed through the investigating the effect of NaCI concentration and current density on EOW performance that the greater the NaCI concentration and current density, the better the EOW performance.
