Description
A rectangular pulse method was applied to evaluate the dry deposition ground surface resistance (Rg) of acetaldehyde (CH3CHO) against three kinds of particles: montmorillonite (MONT), kaolinite (KAOL) and sodium humic acid (HUMIC) samples. It revealed that the order of adsorption or deposition of CH3CHO was MONT > KAOL >> HUMIC. Gas-to-surface exchange rates (kGS), adsorption constants (Kad) and surface reaction rates (kS1) over MONT could be deduced from a series of the rectangular pulse experiments along with a simulated calculation. Rg, which was calculated from kGS, Kad and kS1, increased with relative humidity increasing while kGS was insensitive to relative humidity.
