摘要
Mass accommodation coefficients on aqueous droplets have been measured for two substituted aromatic compounds using a droplet train apparatus and detection in the gas phase by laser induced fluorescence. Values of (1.8+/-0.5) x 10(-2) and (2.7+/-0.5) x 10(-2) have been obtained at 283 K for aniline and phenol, respectively. Mass accommodation of toluene was below the limit of detection of 1.0 x 10(-3). Phenol and aniline are chosen as models for polar and oxygenated species formed as C-y intermediates in the oxidation of less soluble aromatic hydrocarbon precursors. The measurements indicate that mass accommodation of such species could be a significant pathway for the removal of tropospheric hydrocarbons.
