Absorption Efficiency Assessment and Uncertainty Measurement of the Sodium Arsenite Method for Ambient NO2 Determination
Abstract The absorption efficiency and uncertainty involved in the sodium arsenite method (modified Jacobs and Hochheiser method) of NO2 measurement were studied using two standard gas concentrations (4.86 ± 0.10 µmol mol−1 (ppm) and 1.95 ± 0.10 µmol mol−1 (ppm)). An average of 71 ± 3% and 71 ± 6% a...
