The nano-flake graphite and bamboo activated carbon composites (NFG-BAC) were obtained by simple ball-milling and carbonization of bamboo powder and flake graphite at high temperature, which was modified on the surface of the electrode to obtain an electrochemical sensor for the simultaneous separation and determination of hydroquinone (HQ) and catechol (CC). NFG-BAC showed good wettability to electrolyte solution and adsorption capacity to target analytes. NFC-BAC composites possess both the rich porosity and high specific surface area of activated carbon and the good conductivity of nano-flake graphite. Moreover, NFG-BAC composites show good wettability to electrolyte solution and adsorption capacity to target analytes. Compared with the gold-standard methodology for water analysis, electrochemical sensing has fast, sensitive and other advantages. When the NFG-BAC/GCE sensor is used for quantitative analysis of HQ and CC, the linear range is wide (2–1000 μM for HQ and 1–1000 μM for CC), the detection limit is low (0.4 μM for HQ and 0.2 μM for CC), and the detection accuracy of these two pollutants in environmental water samples is high. Due to the sensor fabrication is simple, low-cost and efficient, the NFG-BAC/GCE sensor can be used for real-time monitoring of the pollution of catechol in environmental water samples.

将竹粉和鳞片石墨在高温下进行简单的球磨和碳化得到纳米鳞片石墨和竹活性炭复合材料（NFG-BAC），并在电极表面进行改性，从而获得电化学传感器。同时分离和测定对苯二酚 (HQ) 和儿茶酚 (CC)。NFG-BAC对电解质溶液表现出良好的润湿性和对目标分析物的吸附能力。NFC-BAC复合材料既具有活性炭丰富的孔隙率和高比表面积，又具有纳米片状石墨的良好导电性。此外，NFG-BAC复合材料对电解质溶液具有良好的润湿性和对目标分析物的吸附能力。与水分析的金标准方法相比，电化学传感具有快速、灵敏等优点。NFG-BAC/GCE 传感器用于 HQ 和 CC 的定量分析时，线性范围宽（HQ 为 2-1000 μM，CC 为 1-1000 μM），检测限低（HQ 为 0.4 μM 和CC 为 0.2 μM），对环境水样中这两种污染物的检测精度较高。由于传感器制作简单、成本低、效率高，NFG-BAC/GCE传感器可用于环境水样中儿茶酚污染的实时监测。
