Abstract
This paper presents the results of interlaboratory comparison of analytical data on ion composition for two artificial rain and 80 atmospheric aerosol samples taken on AFA-KhA and Whatman filters. The largest error of analysis is reported for the HCO3- and NH3+ ions. Optimization of the water extraction procedures and improvement of water used for this purpose will reduce the systematic error in aerosol analysis.
