The reaction order with respect to the nitrate ion concentration and the electron number involved in the rate determining step have been determined. The experimental results suggest a reaction scheme the rate determining step of which is NO3→NO3+e....
The particular set of reactivities of nitrogen donors and of peroxodisulfate that make their interactions mechanistically complicated are discussed. Two reactions of this class have been studied experimentally. In the oxidation of nitrite ion by peroxodisulfate, the nitrogeneous product is nitrate. The ra...
The electrons that are necessary for cell carbon fixation are suggested to be delivered by the oxidation of nitrite to nitrate (Eq. (4)) based on the observation that the growth of anammox bacteria appears to be always associated with nitrate production15,16. $${\mathrm{NO}}_2^ - + 2{...

The role of intermediate oxidation states of technetium in catalysis of the oxidation of hydrazine by oxo-anions. Part 1. Nitrate ionsSeparation (TechnologyThe catalysis by technetium of the oxidation of hydrazine by nitric acid has been studied over a wide range of concentrations of hydrazine and...
sulphate, perchlorate or nitrate is oxidized to the corresponding mercuric salts by reaction with oxygen or air in an aqueous acid medium in the presence of a Group VIII metal or silver or gold as catalyst; the metal is unreactive towards the acid. 5-50% metal, e.g. Pd, Pt, or Ag ...

Oxidations of the α-tocopherol model compound 2,2,5,7,8-pentamethyl-6-chromanol. Formation of 2,2,7,8-tetramethylchroman-5,6-dione Overoxidation of 伪-tocopherol (1a) by silver nitrate produces tocored (9a) as a major product. The aim of the present work was to elucidate the pathway...
Sulfite is oxidized in the periplasm by molybdoenzymes that belong to the SO family that is widespread in all three domains of life and also comprises assimilatory nitrate reductase. Arguably, the best characterized enzyme of the SO family is the periplasmic sulfite dehydrogenase SorA from the alp...
