Abstract

The pulse radiolysis of aqueous solutions of NaNO/sub 2/ and NaNO/sub 3/ has been done. In the nitrate solutions the transient species NO/sup 2 -//sub 2/ and NO/sub 2/ have been observed, the former reacting with water to produce NO, the latter dimerizing to N/sub 2/O/sub 4/. In the presence of O/sub 2/ and unidentified species with absorption maximum at 280 nm, probably a peroxy compound, is being formed. The radiolytic processes occurring in the nitrite solution do not depend on /NO/sub 02// and no effect of the direct energy absorption by NO/sup -//sub 2/ has been noticed. Transient species in the diluted nitrate solution are NO/sup 2 -//sub 3/ and the pernitrous ion; in concentrated solutions NO/sub 3/ is the main transient product. NO/sub 3/ is formed by the direct energy absorption by NO/sup -//sub 3/. Participation in tha effect of the cation should not be disregarded. There is evidence that the 340 nm peak in the transient spectrum is probably connected with N/sub 2/O/sub 4/ and not with NO/sub 3/. The tranient spectra, extinction coefficients of products and rate constants of relevant reactions are given.
