摘要
合成了一系列过渡金属的3,3,′3,″3(?)-四硝基酞菁配合物,用不可逆吸附法制备了它们的以玻碳为基体的化学修饰电极(简记为ML CME,M为金属离子,L为酞菁配体).用CV等方法系统地研究了它们的电化学性质特别是电催化性能,本文报道ML CME(M为Fe^(Ⅱ)、Co^(Ⅱ)、Ni^(Ⅱ)和Cu^(Ⅱ))对异菸肼氧化的电催化作用.
The electrochemical behaviors of isoniazide at the 3,3',3',3''-tetranitrophthalocyanine coordination compounds of Fe(??),Co(??),Ni(??)and Cu(??) chemically modified electrodes (ML CMEs, M-metal ion, L-phthalocyaninc) and unmodified glass carbon electrode have been studied for the first time by cyclic voltammctry. Under the same experimental conditions, compared with the unmodified glass carbon electrode, the anodic peak potential of isoniazide atthe ML CMEs shifted negatively obviously, and the anodic peak current of isoniazide increased striking. So the elcctrocatalytic effects of the ML CMEs to the oxidation of isoniazide were striking. There was a very good linear relationship between the peak current of the elcctrocatalytic oxidation and the concentration of isoniazide when the electrodes were the ML CMEs.
