Abstract

In the paper, a high-performance electrode was reported for the determination of uric acid (UA) and dopamine (DA) by loading nanocomposites Fe2O3/poly-neutral red (PNR)/partially reduced graphene oxide (rGO) on glassy carbon electrode (GCE). The nanocomposites Fe2O3/PNR/rGO were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), and electrochemical impedance spectroscopy (EIS). Under the optimized condition, the peak currents of UA and DA showed good linear relationships with their concentrations in the range of 1 × 10–6 to 1 × 10–3 mol L−1 and 3 × 10–7 to 9 × 10–5 mol L−1, respectively. The recovery rates were 93.0–102.0% and 99.2–104.6% for detecting DA from medical injections and human specimens, including urine and serum, respectively, 95.5–105.0% for UA from urine and serum samples. Obviously, this Fe2O3/PNR/rGO/GCE is expected to be used in production quality control and clinical test.

负载部分还原 rGO/GCE 的纳米复合材料 Fe2O3/PNR 作为电化学探针,用于选择性测定尿酸和多巴胺
本文报道了在玻璃碳电极(GCE)上负载纳米复合材料 Fe2O3/聚中性红(PNR)/部分还原氧化石墨烯(rGO),用于测定尿酸(UA)和多巴胺(DA)的高性能电极。扫描电子显微镜(SEM)、X 射线衍射(XRD)、傅立叶变换红外光谱仪(FTIR)和电化学阻抗光谱(EIS)对 Fe2O3/PNR/rGO 纳米复合材料进行了表征。在优化条件下,UA 和 DA 的峰值电流分别在 1 × 10-6 至 1 × 10-3 mol L-1 和 3 × 10-7 至 9 × 10-5 mol L-1 的浓度范围内呈现出良好的线性关系。从医疗注射液和人体样本(包括尿液和血清)中检测 DA 的回收率分别为 93.0-102.0% 和 99.2-104.6%,从尿液和血清样本中检测 UA 的回收率为 95.5-105.0%。显然,这种Fe2O3/PNR/rGO/GCE有望用于生产质量控制和临床检测。
