Photochemical decomposition of several polycyclic aromatic hydrocarbons (including benzo(a)pyrene) proceeds much more slowly when the compounds are adsorbed on coal fly ash than in solution or when adsorbed on other solid surfaces. Certain other polycyclic hydrocarbons (fluorene, the benzofluorenes, 9, 10-dimethylanthracene, and 9, 10-dihydroanthracene) undergo rapid, non-photochemical, degradation when adsorbed onto fly ash surfaces; the extent of this decomposition depends upon the nature of the fly ash.
