Photochemical degradation of selected nitropolycyclic aromatic hydrocarbons in solution and adsorbed to solid particles.
To examine the relationship between the nitro group orientation and photochemical degradation, a series of NPAHs, including 6-nitrochrysene, 9-nitroanthracene and 6-nitrobenzo(a)pyrene were irradiated both dissolved in CH3CN and adsorbed onto a surface (alumina, silica, carbon and cellulose). In solution, not all NPAHs displayed a relationship between their relative and nitro group orientation. In the adsorbed state, the nature of the particle appeared to have more of an influence than did the structure of the NPAH. If the compound degraded, the main product was generally a quinone.
