摘　　要：采用在线分光光度法研究酸性红B废水Fenton氧化降解过程,并通过单因素实验和响应曲面实验对反应条件进行优化。研究表明:Fenton法降解浓度为25 mg/L的酸性红B废水,最佳实验条件为H2O2浓度3.56 mmol/L、Fe2+浓度0.35 mmol/L、pH为2.63,当反应温度为20℃,反应时间为300 s时,降解率可达96.8%;Fenton反应可分为两个阶段:快速降解阶段(反应时间<10 s)和缓慢降解阶段(反应时间>10 s)。Online spectrophotometry was used to study the oxidation degradation process of Acid Red B wastewater by Fenton,and the reaction conditions were optimized by single-factor experiments and response surface experiments.The result shows that the optimal experimental conditions for degrading Acid Red B wastewater by the Fenton method are the concentration of H2O2 of 3.56 mmol/L,the concentration of Fe2+of 0.35 mmol/L,pH of 2.63,and with the dye concentration of 25 mg/L.When the reaction temperature is 20℃,the reaction time is 300 s,the degradation rate can reach 96.8%;the Fenton reaction can be divided into two phases:the first rapid degradation phase(reaction time<10 s)and the second slow degradation phase(reaction time>10 s).
