| Abstract |
An improved method for measuring strong acidity of atmospheric aerosols is presented. An ammonia diffusion denuder was developed to prevent neutralization of the acidic aerosol samples. In addition, a new procedure for protecting samples during shipment and analysis was used. An increase in the sensitivity of the analysis was achieved by extraction of the aerosol sample in a small solution volume, 3 ml, of .0001 N HClO4, and the use of a microelectrode for pH determination. Finally, results from a nine-month study in St. Louis, Missouri and Kingston, Tennessee are given. (Copyright (c) 1988 Pergamon Journals Ltd.) |
