摘　　要：本文采用草酸铁法(UV/Fe(C2O4)33-/H2O2)氧化活性黄染料废水,其动力学模型为拟一级动力学反应,反应速率常数分别为0.01084 s-1,通过动力学研究方法获得染料废水脱色反应的半衰期为68s;考察了pH值和反应温度的变化对氧化反应动力学的影响,初始pH值在3.0～4.0之间,对于草酸铁法羟自由基氧化脱色的反应速率较快;反应温度的升高有利于氧化脱色反应速率的提高,反应的活化能在3～4kJ/mol,属于吸热反应。Using ferrioxalate Act（UV/Fe（C2O4）33-/H2O2） to oxidize the reactive yellow dye wastewater,its dynamic model for the dynamics leave a response,the reaction rate constant For 0.01084 s-1,through the dynamics of different research methods reactive response to the half-life of wastewater decolorization was 68s;inspected the pH and temperature changes in the oxidation Kinetics of the impact of the initial pH value between 3.0 to 4.0,ferrioxalate law decolorization of the hydroxyl radical reaction rate faster reaction to the increase of temperature of the decolorizing reaction rate increase,the reaction of activation In 3 ～ 4 kJ / mol,are endothermic reaction.
