摘　　要： 制备了纳米银/三维石墨烯修饰的玻碳电极并测定对硝基苯酚,通过循环伏安法(CV)和计时电流法(CA)研究其电化学行为.该修饰电极在测定对硝基苯酚时,表现出较正的还原电位和较大的峰电流等优势,并对其实验条件进行优化.结果表明,此传感器制备简单、灵敏性高、稳定性和重现性好,用于硝基苯酚的检测表现出优异的选择性. Nano silver / three-dimensional graphene modified glassy carbon electrode was prepared to determine p-nitrophenol and its electrochemical behavior was studied by cyclic voltammetry （ CV ） and chronoamperometry （ CA ） . The modified electrode display excellent performance in the electrochemical reduction of p-nitrophenol for showing more positive reduction peak potential and high reduction peak currents. The experimental conditions were optimized, the results showed that the sensor has the advantages of simple preparation, high sensitivity, good stability and reproducibility, the detection of p-nitrophenol showed excellent selectivity.
