Chemical reactivity of polycyclic organic compounds adsorbed on coal fly ash and related solid surfaces. Progress report, May 1985-April 1986
The fundamental objectives of this research are to characterize and understand the photochemical and nonphotochemical reactivity of polycyclic aromatic hydrocarbons (PAHs) and their derivatives as adsorbates on the surface of coal fly ash and related particulate solids. Specific efforts undertaken and results obtained during this period are summarized with detailed discussions presented in the form of Appendices. Results are tabulated from a thorough examination of the photochemistry of pyrene, benzo(a)pyrene (BaP), anthracene, phenanthrene, and benz(a)anthracene (BaA) as adsorbates on eight coal stack ashes. A procedure was developed to separate coal ashes into carbon and iron contents. Attempts to measure heats of absorption of PAHs on various coal ashes were made. Pyrene nitration occurred only when NO/sub 2/ was contaminated with nitric acid.
