摘要
通过实验选择了制备铁氰化铜修饰铂电极（CuHCF/Pt）的最佳条件,并用循环伏安法考察了CuHCF/Pt对一价阳离子的选择性及VC在该电极上的电化学行为.实验结果表明,CuHCF/Pt在0.4~1.0 V（vs.SCE）范围内有一对可逆性良好的氧化还原峰,该电极对K＋有较好地选择性且对VC有催化氧化作用.
The best preparation condition of cupric hexacyanoferrate（CuHCF） film modified platinum electrode has been chosen through experiment.The chemical electric behaviours of monovalent cation and ascorbic acid on CuHCF/Pt have been studied by cyclic voltammetry.The result demonstrate that CuHCF film indicate the presence of a couple of well-defined redox peak from 0.4V to 1.0V.CuHCF/Pt exhibits well selectivity of K＋ and catalytic oxidation to ascorbic acid.
