【摘要】 利用层层组装技术,通过Cu2+的桥联作用,制备出铜铁氰自组装膜修饰电极(CuHCF/L-Cys/Au),并研究扫描速度、支持电解质、pH值对该修饰电极电化学性能的影响.结果表明,铜铁氰自组装膜修饰电极具有良好的稳定性和重现性,方法简单易行、干扰小,对对苯二酚具有较好的选择性,其催化电流与对苯二酚浓度在2.0×10-5~2.4×10-4mol.L-1范围呈良好的线性关系.更多还原

【Abstract】 With layer-by-layer assembling technology,another kind of multilayer films CuHCF/L-Cys/Au modified electrode was prepared based on the bridge function of Cu(2+),the effects such as scan rate,electrolyte and pH on the electrochemical properties of the electrode were studied.The experimental results show that the method was simple,small disturbance and CuHCF/L-Cys/Au electrode had good stability and repeatability and high selectivity to hydroquinone.The catalysis currents have good linearity with hydroquinone concentration within the range of 2.0×10(-5)~2.4×10(-4) mol·L(-1).更多还原
