摘　　要：本文通过简单超声法制备了氧化石墨烯-石墨烯(GO-Gr)碳复合材料,通过扫描电镜和电化学方法进行表征。将其修饰在玻碳电极表面,成功构建了用于对乙酰氨基苯酚(APAP)和对氨基苯酚(PAP)检测的电化学传感器。采用差分脉冲伏安法(DPV)测定APAP和PAP,线性检测范围为0.1~70μmol/L和0.3~60μmol/L,检出限为0.02和0.1μmol/L。同时,构建的传感器还表现出良好的稳定性和抗干扰能力,可用于实际样品的检测。In this paper,GO-Gr carbon composites were prepared by simple ultrasound method and characterized by scanning electron microscopy and electrochemical methods.Then it was modified on the surface of the glassy carbon electrode to construct electrochemical sensors for the detection of acetaminophen(APAP)and p-aminophenol(PAP)by differential pulse voltammetry(DPV).The linear detection range of the sensor for APAP and PAP were 0.1~70μmol/L and 0.3~60μmol/L,and the detection limit were 0.02μmol/L and 0.1μmol/L.At the same time,the constructed sensor also showed good stability and anti-interference ability,which could be used for the detection of actual samples.
