| Abstract: | With nicotinamide （3-pyridinecarboxylamide） voltolized by cyclic voltammetry method, polymer film can be prepared on glass carbon electrode to modify electrode, and its effect on NO2 and coexistent ions can be observed. The modified electrode has a sound electrochemical catalytic and selective effect on NO2, differential pulse voltammetry （DPV） can determine that its oxidation current shows linear relations in the intensity of NO2 within 1.68×10^-6 mol/L-1. 76×10^-3 mol/L, correlation coefficient of the linear relations is 0. 999 with the testing range 5.6×10^-7 mol/L. |
