摘　　要：采用沉淀法制备了ZIF-67沸石咪唑酯纳米材料,利用扫描电镜对材料的微观形貌进行了表征。使用ZIF-67纳米材料,成功地构建了一种用于对苯二酚检测的电化学传感器。采用循环伏安法、安培法等方法测定了该电化学传感器的电化学性能。结果表明:ZIF-67/GCE测量对苯二酚的线性范围2.5μmol·L^(-1)~34.5 mmol·L^(-1),检出限是0.83μmol·L^(-1)。研究结果提供了一种检测对苯二酚的新方法,也为其他电化学传感器构置提供了一定的参考与帮助。ZIF-67 zeolitic imidazolium framework ester nanomaterials were synthesized by precipitation method.The microscopic morphology was characterized by scanning electron microscopy.Using ZIF-67 nanoparticles,an electrochemical sensor was successfully constructed for hydroquinone detection.The electrochemical performances of the prepared electrochemical sensor were investigated using cyclic voltammetry and amperometry.The results showed that the linear range of ZIF-67/GCE was 2.5μmol·L^(-1)to 34.5 mmol·L^(-1)for hydroquinone,and the detection limit was 0.83μmol·L^(-1).This research result provides a new method for hydroquinone detection,and also has a certain reference and help for other electrochemical sensor configuration.
