摘要
本研究描述了一种基于碳纳米笼(CNCs)和氧化铜纳米链(CuONCs)的新型高灵敏伏安法技术,用于同时检测内分泌干扰物双酚 A(BPA)和双酚 AF(BPAF)。CNCs 采用溶热法制备,并利用各种技术对其进行了表征。利用 CNCs 和 CuONCs 的纳米复合材料制成的伏安传感器在同时检测双酚 A 和双酚 F 方面表现出色,具有明显的氧化峰和增大的电流峰。伏安法信号与 0.500 μM 至 100 μM 的两种双酚呈线性关系,双酚 A 的检测限为 0.16 µM,双酚 F 的检测限为 0.14 µM。新设计的传感器具有可靠的一致性、长期耐用性和抗干扰能力,在分析实际水样时表现良好,显示出其在环境监测方面的巨大潜力。
Simultaneous determination of bisphenol A and bisphenol AF using a carbon nanocages and CuO nanochains-based sensitive voltammetric sensor
A new and highly sensitive voltammetric technique was described in this study for the concurrent detection of endocrine disruptors bisphenol A (BPA) and bisphenol AF (BPAF) based on carbon nanocages (CNCs) and copper oxide nanochains (CuONCs). The CNCs was prepared by the solvothermal method and characterized using various techniques. Utilizing the nanocomposite of CNCs and CuONCs, the voltammetric sensor demonstrated outstanding performance in detecting BPA and BPAF simultaneously with distinct oxidation peaks and increased current peaks. The voltammetric signals have linear relationships with the two bisphenols ranging from 0.500 μM to 100 μM with a detection limit of 0.16 µM for BPA and 0.14 µM for BPAF. The newly designed sensor showed reliable consistency, long-term durability and anti-interference ability, and performed well in analyzing real water samples, indicating great potential for environmental monitoring.
