Su Anne Lee, Scripps '14, presented a research poster at the American Chemical Society National Meeting in San Diego on March 28th, 2012. Her poster, "Formation of Alylaminium Salts in Particulate Matter," details research that she performed in the laboratory of Professor Katie Purvis-Roberts in summer 2011. Amine gases in the atmosphere derive from sources such as sewage treatment and livestock feeding. Atmospheric reactions between the amines and oxidants, such as the hydroxyl radical, cause aerosols to form. Experiments were done in an Environmental Chamber at the Center for Environmental Research and Technology at the University of California, Riverside. We use a Particle-Into-Liquid Sampler coupled to Ion Chromatographs (PILS-IC) to quantitatively measure the concentration of water soluble ions in aerosols. We determined that amine salts make up a significant portion of the aerosols. The concentration depends on the starting amine, oxidant used, and humidity of the experiment.
