摘要: 采用循环伏安法、线性扫描伏安法及微分脉冲伏安法研究了活性艳蓝X-BR在01mol·l-1KClHCl溶液中的电化学行为.研究发现,在-045V—10VvsSCE电压范围内的循环过程中出现两对氧化还原电流峰,通过考察峰电压随溶液pH值的变化,提出了可能的电极反应机理:阳极区的电极反应是属于失1质子和2电子的氧化反应,而阴极区的电极反应则是蒽醌基团被还原加氢成为氢醌基团的反应.

Abstract: The electrochemical response of reactive brilliant blue X-BR in 0.1mol·l-1 KCl HCl solution was investigated by cyclic voltammetry(CV),linear sweep voltammetry(LSV)and differential pules voltammetry(DPV)methods.The cyclic voltammogram exhibit two couples of current peaks at a potential range of -0.45V—1.0V. A dependence of peak potentials on the pH was estima ted. The possible mechanisms for the electrode reactions were proposed:the irreversible reaction on the positive scan is assumed to be the oxidation of amino group loss of one protons and two electrons.The quasi reversible reaction at the negative branch is considered to be the two electron reduction of anthraquinone and formation of hydroquinone.
