Abstract

The continuous sampling FTIR/AFT (aerosol flow tube) has been constructed in the present work, leading to the in situ observation of the supersaturated solutions of MgSO₄ and NaClO₄ aerosols. The observation suggests that the MgSO₄ aerosol show serious mass transfer limitation at low RH (relative humidity), while the NaClO₄ aerosol deliquesce without notable effect of kinetic factors. It is also shown that the ν₃ band of SO₄^2- is very sensitive to the formation of contact ion pairs in the supersaturated solutions of MgSO ₄ aerosol.
