摘　　要：采用玻碳电极研究了蒽醌类染料的电化学行为.研究发现,由活性艳蓝KN-R表现出的伏安特性可推断出负电位区发生的是蒽醌基和氢醌基的互变反应,正电位区发生的是氨基的氧化反应.由分散红3B的伏安图可推断出在负电位区发生的是蒽醌基的还原,在正电位区存在氨基和羟基的氧化还原反应.而分散蓝2BLN的伏安图能推断出负电位区的蒽醌基的还原反应,但正电位区只能观察到一个氧化峰.The electrochemical behavior of an inone dyes on the surface has been examined. The CV graph of the RBB KN-R indicates that the quasi negative branch is th itive area, the reacti the reduction of an of glassy carbon electrode -reversible reaction at the e anthraquinone and hydroquinone-based interconversion reaction, and in the poson is the oxidation of amido. From the CV graph of the DR 3B, we can infer that raquinone happened in the negative branch, and the reversible reaction assumed to be the redox reation of amino and hydroxyl. In addition, from the CV graph of the DB 2BLN, the reduction of anthraquinone happened in the negative branch, but there is only one anodic peak in the positive area.
