The reduction of nitrous ions, in solutions containing heptane suspended under vigorous stirring and irradiated with a strong UV source, is investigated. The formation of ammonium is used as a monitor of the process which also leads to the concurrent production of organic nitrates and nitrites, as well as of aldehydes and nitro, nitroso and ammino derivatives. An overall mechanism of ammonium formation and destruction is proposed and tested and the effects of NO inf2 sup− concentration, pH, radiation intensity and temperature are evaluated. Implications towards the importance of similar reactions which may occur under sunlight are discussed.
