| Abstract |
The purpose of this investigation was to determine the effects of possible atmospheric interferents on the quantitative collection of sulfuric acid aerosol on a filter. Sulfuric acid aerosol was generated in the laboratory with a flame atomizer and collected on Teflon filters. The filters were exposed to potential gas and vapor interferents and to particulate interferents during, before, or after the collection of the sulfuric acid. Measurements of sulfuric acid were made by an acid-base indicator method or by extraction with benzaldehyde and titration. Also, sulfur evolved on heating the filters was measured by the flame photometric method. Ammonia, particulate calcium carbonate, and ambient particulate material (collected near a busy street) caused severe losses of sulfuric acid; particulate ferric oxide and silicate clay caused an intermediate loss; pyridine and phenol vapors, particulate fly ash, and soot caused little or no loss; and sulfur dioxide and nitrogen dioxide had no effect (in the absence of other materials). |
