General description
Combined effect of NaNO2 and NaCl on the growth of Listeria monocytogenes in tryptone soya broth has been investigated using automated turbidimetric system. Its carcinogenic effects in F-344 rats have been evaluated.
Application
Sodium nitrite may be used as a standard for the quantitative determination of nitrite in culture medium. It may be used in the preparation of isopropyl nitrite, via reaction with isoamyl alcohol.

Journal of hazardous materials, 406, 124774-124774 (2020-12-15)
Futility of traditional advanced oxidation processes (AOPs) in saline wastewater treatment has stimulated the quest for novel "halotolerant" chemical oxidation technology. Acetylacetone (AA) has proven to be a potent photo-activator in the degradation of dyes, but the applicability of UV/AA
