Atmospheric H2SO4 / H2O Particle Formation: Mechanistic Investigations
The formation of H2SO4/H2O particles has been investigated in a laboratory study using a flow tube operated at atmospheric pressure. The needed H2SO4vapour was produced in three different ways: (i) in situ formation starting from OH + SO2, (ii) reaction of SO3 with water vapour, (iii) taking H2SO4vapour from a liquid reservoir. The findings are discussed with respect to the mechanism of the formation of particle’s precursors.
