The uptake of 2-nitrophenol, 2-methylphenol, 3-methylphenol, and 4-methylphenol on aqueous surfaces was
investigated between 278 and 303 K, using the wetted-wall flow tube technique coupled with UV absorption
spectroscopic detection. The uptake coefficients γ were found to be independent of the aqueous phase composition and of the gas−liquid contact times. In addition, the uptake coefficients and the derived mass accommodation coefficients α show a negative temperature dependence in the temperature range studied. The mass
accommodation coefficients decrease from 5.2 × 10<sup>-3</sup> to 8.3 × 10<sup>-4</sup>, from 5.0 × 10<sup>-3</sup> to 3.1 × 10<sup>-4</sup>, from
6.7 × 10<sup>-3</sup> to 7.3 × 10<sup>-4</sup>, and from 1.2 × 10<sup>-2</sup> to 5.9 × 10<sup>-4</sup> for 2-nitrophenol, 2-methylphenol, 3-methylphenol, and 4-methylphenol, respectively. These results are used to discuss the incorporation of these species
into the liquid using the nucleation theory. These data combined with the Henry's law constants were used
to estimate the partitioning of the phenolic compounds between gaseous and aqueous phases and the
corresponding atmospheric lifetimes under clear sky (τ<sub>gas</sub>) and cloudy conditions (τ<sub>multiphase</sub>) have then been
derived.
