本文采用一步高温热分解法制备了石墨相氮化碳（g-C3 N4），并采用浓盐酸质子化法制备了层状g-C3 N4。采用透射电子显微镜（TEM）、能谱仪（EDS）和X射线粉末衍射仪（XRD）对产物的形貌和组成进行了表征。采用涂层法和恒电位沉积法制备了AuNPs-g-C3 N4/GCE电极，并通过循环伏安法（CV）和电化学阻抗谱（EIS）对电极的制备过程和电阻变化进行了表征。实验结果表明，AuNPs-g-C3 N4/GCE对双酚A（BPA）和对辛基苯酚（OP）具有良好的电催化性能。在优化的实验条件下，以AuNPs-g-C3 N4/GCE为载体，采用示差脉冲伏安法（DPV）对BPA和OP进行了检测。BPA和OP的线性范围分别为0.1-6.5 μmol L−1和0.1-3.8 μmol L−1，检测限分别为0.0176 μmol L−1和0.0324 μmol L−1。此外，AuNPs-g-C3 N4/GCE具有良好的重现性和稳定性，可成功应用于婴儿配方奶粉中BPA和OP的检测。
In this paper, graphite phase carbon nitride (g-C3N4) was prepared by one-step high temperature thermal decomposition method, and layered g-C3N4 was prepared by protonation with concentrated hydrochloric acid. The morphology and composition of g-C3N4 were characterised by transmission electron microscope (TEM), energy dispersive spectroscopy (EDS) and X-ray powder diffraction (XRD). Furthermore, the AuNPs-g-C3N4/GCE was constructed by coating method and potentiostatic deposition method, and the construction process and resistance change of the electrodes were characterised by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The experimental results indicated that the AuNPs-g-C3N4/GCE has excellent electrocatalytic performance for bisphenol A (BPA) and 4-n-octylphenol (OP). Under optimized experimental conditions, BPA and OP were detected by differential pulse voltammetry (DPV) at the AuNPs-g-C3N4/GCE. The linear ranges were 0.1–6.5 µmol L−1 and 0.1–3.8 µmol L−1 for BPA and OP, wtih the detection limits of 0.0176 µmol L−1 and 0.0324 µmol L−1, respectively. In addition, the AuNPs-g-C3N4/GCE showed satisfactory reproducibility and stability and can be successfully applied to monitor of BPA and OP in baby formula samples.
