摘　　要：目的研究几种典型的制备酸性氧化电位水(EOW)的商用电极的性能,并评价了其所制备的EOW水质、能耗与杀菌效果。为制备EOW的电极选择涂层金属元素和制备涂层钛阳极提供参考。方法采用扫描电镜(SEM)观察、析氯/析氧电位、强化寿命测试及悬液定量杀菌试验进行研究。结果 B3和B4都是呈典型龟裂"岛状"形态的涂层钛电极,含较多Ru、Ir及少量Pt元素,表面细小簇状晶粒的析出有助于提高涂层活性;B3和B4的析氧电位较低,与其涂层上含有的对析氧反应具有优良催化活性的RuO2和IrO2有关;电极寿命大小为:B3>B4>B2,水质达标时单位能耗为:B2>B4>B3。结论电极性能受涂层成分、活性组元素含量、结构形貌等因素的影响;B2、B3和B4对析氯反应的催化活性高于析氧反应,都是偏析氯型电极;用B4制备的EOW对金黄色葡萄球菌具有较强的杀灭能力。Objective To investigate the property of typical business electrodes for making electrolyzed oxidizing water（EOW） and to evaluate the quality,energy consumption and disinfection effect of EOW so as to provide the reference for choosing the coated metallic element and preparing the titanium（Ti） coated electrode.Methods The scanning electron microscope（SEM）,chlorine evolution/ oxygen evolution potential test,strengthening life test and the suspension quantitative bactericidal test were used to study the typical business electrodes＇ property and quality of EOW.Results The B3 and B4,which were electrodes coated by Ti and contained Ru,Ir,Pt,presented the typical cracked ＂island＂ pattern.The tiny clustered grains separated out from the surface of the B3 and B4 electrodes contributed to improve the coating＇s activity.The oxygen evolution potentials of B3 and B4 were low which correlated with the excellent catalytic activity of RuO2 and IrO2 in the oxygen evolution reaction.The lifetime of electrodes were as following ： B3B4B2;the energy consumption to reach the standard of water quality were as following： B2B4B3.Conclusion The electrode＇s property is affected by the coating＇s component,ratio of active ingredient,structure and morphology.B2,B3 and B4 have the higher catalytic activity in the chlorine evolution reaction than in the the oxygen evolution reaction and they are all the electrodes of chlorine evolution type.The EOW prepared by B4 has stronger germicidal effect on the staphylococcus aureus.
