This paper reports a voltammetric sensor based on copper oxide nanoparticles on nitrogen-doped reduced graphene oxide nanocomposite (N-rGO/CuO)-ionic liquid modified carbon paste electrode (N-rGO/CuO-ILCPE) for determining the hydroquinone (HQ). The N-rGO/CuO was prepared by a facile protocol, followed by characterization via fourier transform-infrared (FT-IR) patterns, field emission-scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) analysis. The electrochemical behaviour was linearly symmetrical to various hydroquinone levels (1.0-600.0 μM) with a narrow limit of detection (LOD = 0.25 μM). The diffusion coefficient was also estimated to be 4.1 × 10 cm/s. The N-rGO/CuO-ILCPE was impressively applicable in determination of hydroquinone in the real specimens.
本文报道了一种基于氧化铜纳米粒子在氮掺杂还原氧化石墨烯纳米复合材料（N-rGO/CuO）-离子液体修饰碳糊电极（N-rGO/CuO-ILCPE）上的伏安传感器，用于测定对苯二酚（HQ）。N-rGO/CuO 通过简便的方案制备，随后通过傅里叶变换红外（FT-IR）图谱、场发射扫描电子显微镜（FE-SEM）、能谱（EDX）和 X 射线衍射（XRD）分析进行表征。电化学行为对各种对苯二酚水平（1.0-600.0 μM）呈线性对称，检测限低（LOD = 0.25 μM）。还估计了扩散系数为 4.1×10 cm/s。N-rGO/CuO-ILCPE 令人印象深刻地适用于实际样品中对苯二酚的测定。
