摘　　要：以一种基于双金属体系的新型三元微电解填料为研究对象,通过循环伏安法和紫外光谱扫描对其降解2,4-二硝基苯酚废水机理进行了初步探究。通过对2,4-二硝基苯酚溶液进行循环伏安法测定,模拟铁碳微电解填料对2,4-二硝基苯酚溶液的电化学催化降解过程。研究pH、温度、DO、电导率等试验因素下在2,4-二硝基苯酚降解过程中对循环伏安曲线的影响。结果表明:新型铁碳微电解填料对2,4-二硝基苯酚的降解过程包含电化学催化还原作用。A new kind of ternary micro electrolysis fillers based on bimetallic system were chosen as the research object.Mechanism of how the filler degrades 2,4-dinitrophenol wastewater was discussed carefully by cyclic voltammetry method and UV spectroscopy.Through the determination of cyclic voltammetry,the electrochemical catalytic degradation process of Fe/C filler for 2,4-dinitrophenol solution was simulated.Reaction pH,temperature,DO and conductivity were the four factors studied to observe the impacts on cyclic voltammetry curves.Study results showed that the degradation of Fe/C fillers for 2,4-dinitrophenol was due to electrochemical catalytic reduction.
