摘要：
Histidine monolayer was adsorbed on the surface of the gold electrode in aim to investigate electrochemical behavior of Cu2+ ion and Cu-His complex. Formation of the layer on the gold surface was investigated with cyclic voltammetry with p-benzoquinone/hydroquinone redox pair. Interaction between the modified electrode and Cu2+ and Cu-His was characterized with cyclic voltammetry and adsorptive anodic stripping voltammetry. Coupling of the Cu2+ and Cu-His onto the modified electrode was successfully done for a wide range of tested concentrations. Electrode response was linearly proportional to log c(Cu2+) and log c(Cu-His) with correlation coefficient R-2 = 0.9945 and R-2 = 0.9807 respectively.
