At fixed aerosol acidity, we recently demonstrated that dimers in isoprene epoxydiol-derived secondary organic (IEPOX-SOA) can heterogeneously react with hydroxyl radical (·OH) at faster rates than monomers. Aerosol acidity influences this aging process by enhancing the formation of oligomers freshly generated IEPOX-SOA. Therefore, systematically examined role on kinetics and products resulting from heterogeneous ·OH oxidation IEPOX reacted inorganic sulfate varying initial pH (0.5, 1.5,...
Oxidation of isoprene, the biogenic volatile organic compound (BVOC) with highest emissions globally, is a large source secondary aerosol (SOA) in atmosphere. Particulate organosulfates formed from acid-driven reactions oxidation products isoprene epoxydiol (IEPOX) isomers are important contributors to SOA mass. Most studies have focused on organosulfate formation ammonium sulfate particles, often at low pH. However, recent work has shown that sea spray (SSA) accumulation mode (∼100 nm)...
