摘　　要：制备了石墨烯修饰电极,研究了去甲肾上腺素(NE)在修饰电极上的电化学行为,实验结果表明,石墨烯修饰电极对去甲肾上腺素有明显的催化作用。在pH=5的柠檬酸-磷酸氢二钠的缓冲溶液中,NE的氧化峰电流与浓度在9.2×10-7～2.3×10-5mol/L范围内呈线性关系,检出限为4.6×10-8mol/L。修饰电极表现出良好的稳定性。Graphene modified glassy carbon electrode was prepared, and the electrochemical behaviors of norepi-nephrine was studied on this modified electrode. Experimental results showed that the graphene modified electrode had excellent catalytic properties for redox of norepinephrine. In PBS （ pH = 6） solution, the oxidation peak current was linear with the concentration of NE in the range of 9.2×10^（-7）～2.3×10^（-5）mol/L. The detection limit was4.6×10^（-8）mol/L. The modified electrode showed a good stability
