Abstract |
The determination of atmospheric sulfur dioxide as aqueous bisulfite using 5,5'-dithiobis(2-nitrobenzoic acid) (DTBN) was validated as a simple, rapid and reliable procedure. Standard sulfur dioxide concentrations in air (0-2.6ppm) were generated by means of a permeation device. Sulfur dioxide from air samples was absorbed in pH7 phosphate buffer and determined as bisulfite. The mean percentage recovery of sulfur dioxide is 101.4; the slope of the validation line determined by linear regression analysis is 1.014 found/calculated (1.4% absolute error; 0.9976 correlation coefficient). |
