Abstract:

Nitropolycyclic hydrocarbons (NPAHs) are environmental pollutants that consist of several fused aromatic rings containing one or two nitro (NO2) groups attached to the aromatic rings. It is thought that the photodegradation of NPAHs is related to the geometrical orientation of the nitro groups. To test this hypothesis, the effect of irradiation on 6-nitrochrysene, 9-nitroanthracene and 6-nitrobenzo(a)pyrene has been investigated, when both the NPAHs are dissolved in CH3CN solution and when they are adsorbed onto various solid surfaces. In solution, there appears to be no clear relationship between the photodegradation and the orientation of the nitro groups while, in the solid-state, the nature of surface does have some influence.
