摘　　要：用化学方法测定了偶氮苯最初的COD值,通过对电生成Fenton试剂对偶氮苯染料废水降解的动力学分析表明,偶氮苯的降解反应近似遵循一级反应动力学特征.在电生成Fenton试剂的过程中,有机物的去除率超过80%,有效降低了染料废水的浓度、色度和COD值.The degradation of azobenzene dyes in aqueous solution at room temperature is studied by an advanced electrochemical oxidation process （AEOPs） under potential-controlled electrolysis conditions, using a Pt anode and a carbon-felt cathode. The COD of the azobenzene dyes is determined by chemical method. Kinetic analysis of these data shows a pseudo-first order degradation reaction for azobenzene. The result displays that the removal rate of oganics is 80 %.
