A dihydroxybenzene isomers electrochemical sensor based on bamboo activated carbon (MCPBAC) sensitive material activated by mechanochemistry and low-dosage phosphoric acid was fabricated in this work. The sensor, modified by MCPBAC with GCE, can significantly distinguish and sensitively measure hydroquinone (HQ) and catechol (CC). The MCPBAC exhibits a well-developed porous structure, high specific surface area, and good electrical conductivity. Using differential pulse voltammetry (DPV), wide linear ranges for both HQ and CC are 0.6-600 μM, with low detection limits (S/N = 3) for both of 0.2 μM. The dihydroxybenzene isomers electrochemical sensor has wide application prospects in the determination of trace HQ and CC in environmental water.
本工作制备了一种基于竹基活性炭（MCPBAC）的二羟基苯异构体电化学传感器，该传感器通过机械化学和低剂量磷酸活化。修饰后的 MCPBAC 与 GCE 结合，可显著区分和灵敏地测量对苯二酚（HQ）和邻苯二酚（CC）。MCPBAC 具有发达的多孔结构、高比表面积和良好的导电性。采用差分脉冲伏安法（DPV），HQ 和 CC 的线性范围均为 0.6-600 μM，检测限（S/N = 3）均低至 0.2 μM。该二羟基苯异构体电化学传感器在环境水样中痕量 HQ 和 CC 的测定方面具有广阔的应用前景。
