摘要：
Carbon-nanotube modified glassy carbon ceramic composite electrodes exhibiting strong electrocatalytic response toward the reduction of nitrite are described. The effects of PH value of detection solution and applied potential on the current response of nitrite reduction are also discussed. Under optimal conditions, the modified electrode shows a linear response to nitrite in the concentration range from 5 x 10(-5) to 3 x 10(-3) mol/L, and the detection limit is 2 x 10(-5) mol/L at a signal-to-noise ratio of 3.
