In the present work, an efficient electrochemical sensor based on poly (Orange CD) fabricated carbon paste electrode (FCPE) was constructed which displayed effective electrochemical response toward 3, 4-dihydroxyphenethylamine (DHPA) and uric acid (UA). The various parameters like the effect of scan rate, pH & concentration of DHPA were studied. The scan rate effect was found to be an adsorption controlled electrode process. The pH study exposes the participation of an equal number of protons and electrons in the redox mechanism. The detection limits of 0.41 and of 0.63 μM were achieved for DHPA & UA analysis. The sensor was stable, sensitive, selective, and reproducible. The practical application of poly (Orange CD) FCPE revealed satisfactory recovery.

在目前的工作中，基于聚（橙色CD）制造的碳糊电极（FCPE）的高效电化学传感器被构建，该传感器对3，4-二羟基苯乙胺（DHPA）和尿酸（UA）表现出有效的电化学响应。研究了各种参数，如扫描速度，pH和DHPA浓度的影响。发现扫描速率效应是吸附控制的电极过程。pH研究揭示了相同数量的质子和电子参与氧化还原机理。DHPA和UA分析的检出限达到0.41和0.63μM。该传感器是稳定，灵敏，选择性和可重现的。聚（橙色CD）FCPE的实际应用显示令人满意的回收率。
