Effects of two transition metal sulfate salts on secondary organic aerosol formation in toluene/NO

Biwu CHU, Jiming HAO, Junhua LI, Hideto TAKEKAWA, Kun WANG, Jingkun JIANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 1,   Pages 1-9 doi: 10.1007/s11783-012-0476-x

Abstract: Aerosol phase reactions play a very important role on secondary organic aerosol (SOA) formation, andThese observations are consistent when varying metal sulfate aerosol concentrations.Their subsequent partitioning into the aerosol phase leads to the observed SOA formation enhancement.
