Simultaneous determination of SO(2), NO and NO(2) in air by differential pulse polarography.
The method of Garber and Wilson for SO(2) determination has been tested on real samples of air. The results demonstrate the possibility of simultaneous determination of SO(2), NO and NO(2) in the sample. Detection limits as low as 7 mul/m(3) for SO(2) and about 50 mul/m(3) for nitric oxides can be reached.
