Presentation Title
The effect of deliquescence and efflorescence on particle phase for an ammonium and sulfate salt series
Abstract
Aerosols play multiple important roles in the environment: they directly affect climate patterns by absorbing and scattering radiation, and they provide a site for reaction to occur. It is necessary to understand the dynamic particle phase of these aerosols, which will in turn shed light on how they affect the environment. Deliquescence occurs when the water content of an aerosol particle becomes great enough for the analyte to dissolve in the water. In opposition, efflorescence of an aerosol analyte occurs when the water content decreases to the point of the salt falling out of solution. In this study, aerosolized salt solution behavior will be examined for both deliquescence and efflorescence. This will be done by carrying out a series of proof-of-principle experiments based on the model, ammonium sulfate. As ammonium sulfate deliquescence and efflorescence produces data with clear trends, a series of ammonium salts and sulfate salts will be examined.
