阴极材料对甲基橙电化学脱色影响的研究

采用具有催化作用的钛涂钌材料作为阳极,分别以泡沫镍、不锈钢、钛涂钌等不同材料作为阴极构成电解体系,系统地研究了阴极材料的性质和形状对模拟染料甲基橙的电解脱色影响,分析了电化学体系内甲基橙脱色的机理,采用隔膜电解槽研究了阴、阳极对甲基橙的脱色效果.结果表明,在相同的控制条件下,几种阴极构成的电化学体系中,甲基橙脱色的效果由强到弱依次为:泡沫镍>钛涂钌>不锈钢材料.无论是无隔膜电解体系还是隔膜电解体系,通过阴、阳极协同电催化氧化作用,对水中染料均有很好的脱色效果,该方法具有很好的应用前景.

Study of Effect of Different Cathodes on Decoloring Methyl Orange by Electrochemical Method

Effects of the properties and shape of cathode on removal rate of color were systematically studied in an undivided electrolytic cell with an anode of electrocatalytic activity as well as a cathode of foam nickel, stainless steel, Ti/RuO2. The mechanism of decolorization of the simulated dye solution was analyzed in electrochemical system and the effect of anode and cathode on degradation of simulated dye solution by electrochemical treatment in the divided cell was studied and.With the same condition, for decoloring Methyl orange, the electrochemical catalytic effectiveness of the four cathodes was: foam nickel > Ti/RuO2> stainless steel. Above all, the electrolysis cell, whether or not there was diaphragm, can be used to treat the dye - containing wastewater by synergetic effects of anodic-cathodic. As a result, the electrochemical method was a promising technology in dye wastewater.
