摘要
通过元素分析,电解水电极片主要为含钌、铱氧化物涂层材料,部分产品添加贵金属铂。运用MiniTab软件,通过DOE实验设计,并进行拟合回归模型分析,得出有效氯浓度的回归方程,其R-sq(调整)为95.83%,所建模型的拟合度较好。杀菌试验得出,对于水体杀菌,电解水有效氯浓度大于0.35 mg/L时,1 min内对大肠肝菌的杀菌率达99.9%以上。对于陶瓷表面杀菌,有效氯浓度、电解水量及作用时间均对杀菌率有影响,应保证电解水中有足够的有效氯总量(C~*V)与细菌作用,当有效氯总量较低时,延长杀菌时间,可以提高杀菌率。对于自制电解水加湿器,表面杀菌率较低,电解水雾气对布片的杀菌率(55%)略高于对陶瓷表面的杀菌率(27%)。
Through elemental analysis,the electrodes are mainly coated with ruthenium and iridium oxides,and some electrodeproducts contain precious metal platinum.Using MiniTab software,the electrolytic performances of the electrolytic modules were analyzed by DOE experimental designs.By fitting the regression mode4ls,the regression equations of effective chlorine concentration were obtained,and the R-sq(adjusted)were 95.83%,meaning the fitting degree of the established models was good.For water sterilization,the sterilization rate of E.coli can reach above 99.9%within 1 min,when the effective chlorine concentration is greater than 0.35 mg/L.For the sterilization of ceramic surface,the sterilization rates are effected by the effective chlorineconcentration,the amount of electrolytic water and the acting time.It is necessary to ensure that there is enough effective chlorine(C*V)in the electrolytic water to interact with bacteria.When the total amount of effective chlorine is low,prolonging the acting time can improve the sterilization effect.For self-made electrolytic water humidifier,the surface bactericidal rate is low,and the bactericidal rate of electrolytic water mist on cloth(55%)is slightly higher than that on ceramic surface(27%).
