摘　　要：文章旨在探索电催化技术在去除工业废水中铅离子(Pb^(2+))的效果,通过单因素实验和响应面法多因素实验,确定了最佳反应条件为电压7.5 V、电流密度65 m A/cm^(2)、反应时间65 min、p H值7.5。在此条件下,Pb^(2+)去除率达91.2%。动力学分析表明,Pb^(2+)的去除过程符合一级反应动力学模型,反应速率常数为0.035 min^(-1)。电催化反应中Pb^(2+)的去除主要是通过阴极表面的还原反应实现,优化电极材料和反应条件可显著提高去除效率。研究结论可为电催化技术在处理含铅工业废水的应用提供科学依据和技术支持。This article aims to explore the effectiveness of electrocatalytic technology in removing lead ions(Pb^(2+))from industrial wastewater and optimize the reaction conditions.Through single-factor experiments and response surface methodology,the optimal reaction conditions were determined,the voltage is 7.5 V,current density is 65 mA/cm^(2),reaction time is 65 minutes and pH value is 7.5.Under these conditions,the Pb^(2+)⁺removal rate reached 91.2%.Kinetic analysis showed that the removal process of Pb^(2+)⁺followed a first-order kinetic model with a rate constant of 0.035 min⁻¹.The removal of Pb²⁺in the electrocatalytic reaction was primarily achieved through re-duction reactions on the cathode surface.Optimizing the electrode materials and reaction condi-tions significantly improved the removal efficiency.The results provided scientific evidence and technical support for the application of electrocatalytic technology in treating organophosphate pes-ticide wastewater.
