【摘要】 研究了亚甲基兰在以活性炭为电极材料的三维电极上电化学降解过程,讨论了溶液流速、溶液初始质量浓度以及电解电流对亚甲基兰降解的影响,对反应过程进行了动力学分析并对反应机理进行了探讨。结果表明,亚甲基兰溶液质量浓度随反应时间成直线下降,亚甲基兰降解率与初始质量浓度成反比关系、与电解电流成正比关系。反应符合零级反应,电化学降解反应为控制步骤。更多还原

【Abstract】 The electrochemical degradation mechanism of Methylene blue on the active carbon electrode in the three dimensions electrode was studied.The influence of velocity of flow,initialization concentration and electrical current were discussed.The kinetics and mechanism of the reaction was studied.The result of the test: the concentration of Methylene blue was linearly reduced with the reaction time,the degradation ratio was inverse proportion with the initialization concentration,and was direct proportion with the electrical current.The reaction was accorded with the characteristic of 0-grade reaction,The electrochemical degradation was the control process.更多还原
