| Research Abstract |
Dry deposition surface resistance is an important input data for air quality model. Rectangular pulse experiments with a stirring chamber were used to determine dry deposition surface resistance of SO2 and aldehydes on powder samples such as clay minerals under different relative humidities. The deposition surface resistance was distinguished from adsorption and depends on hygroscopic characteristic of the test powder samples.
The activation Gibbs free energy changes of hydration, that is, diol formation reaction for a series of aldehydes were calculated using a water-cluster and polarizable continuum hybrid model. Good correlation between the calculated values and available experimental ones could evaluate the experimentally unavailable rate constants for diol formation of aldehydes in aqueous solution.
