Abstract/OtherAbstract:
|
Humic substances that preferentially adsorb at the air/water interfaces of water or aerosols consist of both fulvic and humic acid. To investigate the chemical reactivity for the heterogeneous reaction of gaseous ozone, O3(g), with aqueous iodide, I-(aq), in the presence of standard fulvic acid, humic acid or alcohol, cavity ring-down spectroscopy was used to detect gaseous products, iodine, I2(g) and an iodine monoxide radical, IO•(g). Fulvic acid enhanced the I2(g) production yield, but not the IO•(g) yield. Humic acid, n-hexanol, n-heptanol and n-octanol did not affect the yields of I2(g) or IO•(g). We can infer that the carboxylic group contained in fulvic acid promotes the I2(g) emission by supplying the requisite interfacial protons more efficiently than water on its surface. |
