Abstract:


The electrochemical bahaviour of cysteamine (CA) has been investigated by synergic effect of acetylferrocene (AF) and NiO/CNT nanocomposite at a surface of carbon paste electrode (AF/NiO/CNTs/CPE). Voltammetric techniques were used to investigate the suitability of AF/NiO/CNTs/CPE for the electrocatalytic oxidation of CA in pH=7.0 as a suitable condition in voltammetric analysis. AF/NiO/CNTs/CPE shows a dynamic range to electrocatalytic analysis of CA in the range of 0.1-600 µ M with a detection limit of 0.07 µ M by square wave voltammetric method (SWV). The ability of AF/NiO/CNTs/CPE as a sensor checked analysis of CA in real samples.
