Apstrakt
In this study an analytical system was developed for determination of quantitative characteristics of BTEX distribution between gaseous and aqueous phase. Dynamic dilution system was coupled with Proton Transfer Reaction Mass Spectrometer (PTR-MS) to provide conditions for partitioning between the two phases resembling the interactions during rainfall. The amount of the target species retained in water were significantly higher than suggested by theoretical predictions indicating that dissolution is not the major mechanism of gaseous BTEX uptake in aqueous phase. Distribution coefficients and enrichment factors were calculated, and the possible mechanisms of partitioning were considered. As concluded, the interfacial adsorption and van der Waals interactions play significant role, whereas hydrogen-bond interactions have no major contribution to BTEX partitioning.
