Rotating-disc electrode determination of nitrogen dioxide concentrated in N,N-dimethylformamide.
Nitrogen dioxide at ppm levels in air is concentrated in N,N-dimethylformamide and determined by voltammetry at a rotating-disc electrode. The oxidation currents for nitrite are measured under the same conditions as the nitrogen dioxide reduction and are used as standards. The results are in good accordance with the values calculated from the absorption measurements.
