| 摘 要：為實(shí)現鄰苯二酚（HQ）和對苯二酚（CA）的快速、靈敏檢測，以NaCl作為模板、葡萄糖酸鋅（sodium gluconate）為碳源，通過(guò)溶解-重結晶制備碳前驅體，同時(shí)熱解制備多孔碳材料（ZGDPC）并將其用于構建電化學(xué)傳感器ZGDPC／GCE。使用掃描電子顯微鏡（SEM）、X射線(xiàn)粉末衍射（XRD）及比表面積分析儀分別對其形貌和結構進(jìn)行了表征，然后通過(guò)差分脈沖伏安法（DPV）考察了ZGDPC／GCE表面HQ和CA的電化學(xué)行為。優(yōu)化條件下，HQ 的線(xiàn)性檢出范圍為0~25 μmol／L，檢出限為0.124 μmol／L，CA的線(xiàn)性檢出范圍為0~30 μmol／L，檢出限為0.213 μmol／L。該傳感器對實(shí)際水樣中HQ和CA的回收率為95.6%~102.3%。以上結果表明，基于該電化學(xué)傳感器能實(shí)現實(shí)際樣品中對HQ和CA的同時(shí)檢測。 |

| Abstract：In order to realize the rapid and sensitive detection of catechol (HQ) and hydroquinone (CA), NaCl was used as template and sodium gluconate was used as carbon source, the carbon precursor was prepared through a process including dissolving and recrystallization. Porous carbon material (ZGDPC) was prepared by pyrolysis of the above carbon precursor and used to construct electrochemical sensor ZGDPC/GCE. The morphology and structure of ZGDPC/GCE were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and specific surface area analyzer, respectively. Then, the electrochemical behavior of HQ and CA on ZGDPC/GCE surface was investigated by differential pulse voltammetry (DPV). Under the optimal conditions, the linear detection range of HQ was 0~25 μmol/L with a detection limit of 0.124 μmol/L, and the linear detection range of CA was between 0 and 30 μmol/L with a detection limit of 0.213 μmol/L. In addition, the recovery rate of HQ and CA in actual water samples was between 95.7% and 102.3%. The above results showed that the electrochemical sensor could not only realize the simultaneous detection of HQ and CA, but also can be applied to actual sample analysis. |
