  • 摘要: 以自制Ti基RuO2-IrO2镀层形稳电极为阳极,采用电催化氧化处理偶氮染料甲基橙模拟废水。以硫酸钠为支持电解质,在自然pH条件下分别考察了电解时间、电极间距、电流密度和电解质浓度等因素对甲基橙去除率的影响,并分析其原因。实验结果表明,在自然pH、电极间距为1.0 cm、电流密度为30.0 mA/cm2、电解质硫酸钠浓度为20.0 g/L、电解1.0 h,甲基橙去除率高达90.0%以上。 因此,电催化氧化法作为一种高效、简便的染料废水处理技术,具有一定的应用潜力。
    Abstract: Using a home-made stable anode with Ti-base and RuO2-IrO2-coating,electro-catalytic oxidation was applied to treat analog azo dyes wastewater methyl orange solution.The investigation focused on the effects of electrolysis time,electrode interval,current density and electrolyte concentration on the removal of methyl orange in the electrolytic process.Also,the causes were analyzed.The experiments show that the methyl orange removal rate is up to 90.0% under the condition of natural pH,electrode interval of 1.0 cm,current density of 30.0 mA/cm2,electrolyte concentration of 20.0 g/L,electrolysis of 1.0 h.Therefore,as a highly efficient,easy dye wastewater treatment technology,the electro-catalytic oxidation method has certain application potential.
