摘　　要：目的:制备了木犀草素修饰碳糊电极(Luteolin-PCE),研究了Luteolin-PCE的电化学行为,探讨了酸度对Luteolin-PCE电化学性质的影响。方法:用循环伏安法研究了Luteolin-PCE的电化学性质。结果:发现Luteolin-PCE存在一对可逆的氧化还原峰,其半波电位与酸度成线性关系,电子转移数目对酸度有依赖性。Objective: To study the electrochemical behavior of luteolin-PCE and the effect of acidity on its electrochemistrical properties. Method: Luteolin modified carbon paste electrode (luteolin-PCE) was prepared. The electrochemistrical properties of luteolin-PCE were studied by cyclic voltammetry (CV). Result: There was a couple of reversible redox peaks, and the redox potentials were found to be pH dependent. The number of electron transferr was related to acidity.
