Abstract
Recent field and experimental studies have suggested that acid-base reactions of alkylamines may play an important role in secondary aerosol formation. We investigated the heterogeneous chemistry of ethylamine (EA), diethylamine (DEA) and triethylamine (TEA) on liquid H2SO4 (1 wt%–80 wt%). Irreversible reactive uptakes were observed for all three alkylamines. The reactive uptake coefficients (γ) of alkylamines increased with the acid concentration, and the γ value for DEA appeared to increase slightly faster than that of EA and TEA. The potential roles in secondary aerosol formation of different alkylamines are briefly discussed.
