A novel imprinted electrochemical sensor based on graphene/carbon nanotubes three-dimensional (3D) nanocomposites modified carbon electrode was developed for the determination of tetrabromobisphenol A. The imprinted film was prepared by one-step electrodeposition technique with pyrrole as the functional monomer and tetrabromobisphenol A as the template molecule. The imprinted sensor was used for the determination of tetrabromobisphenol A with differential pulse voltammetry. A linear relationship between the response currents and the negative logarithm of tetrabromobisphenol A concentrations was obtained in the concentrations range of 1.0×10(-11)-1.0×10(-8) mol L(-1) with a detection limit of 3.7×10(-12) mol L(-1) (S/N=3). The proposed imprinted sensor showed excellent selectivity towards tetrabromobisphenol A. With good reproducibility and stability, the imprinted electrochemical sensor was used to detect tetrabromobisphenol A in fish samples successfully with the recoveries of 93.3-107.7%.
基于石墨烯/碳纳米管三维（3D）纳米复合材料修饰碳电极，开发了一种用于测定四溴双酚 A 的新型印迹电化学传感器。印迹膜采用一步电沉积技术，以吡咯为功能单体，四溴双酚 A 为模板分子制备。采用差分脉冲伏安法测定四溴双酚 A。在 1.0×10(-11)-1.0×10(-8) mol L(-1)浓度范围内，响应电流与四溴双酚 A 浓度的负对数呈线性关系，检测限为 3.7×10(-12) mol L(-1)（S/N=3）。该印迹传感器对四溴双酚 A 表现出优异的选择性。该印迹电化学传感器具有良好的重现性和稳定性，成功用于鱼样中四溴双酚 A 的检测，回收率为 93.3-107.7%。
