Kinetics Analysis of the Reactions between Peroxynitric Acid and Amino Acids
Chemical Research in Toxicology, 2020Plasma disinfection using low-temperature atmospheric pressure plasma is widely studied in many applications, and the use of plasma-treated water (PTW) for disinfection is being developed by many researchers. Exposing plasma to water supplies and preserves reactive oxygen and nitrogen species (RONS) in the water, and this PTW exhibits bactericidal ...

Significance of peroxynitric acid in atmospheric chemistry of nitrogen oxides
Nature, 1977KNOWLEDGE of the life cycle and budget of nitrogen oxides in the atmosphere is important for several reasons. In the stratosphere, NO and NO2 (NOX) play a dominant part in maintaining the structure and stability of the ozone distribution. In the troposphere, NOX is involved in the production and destruction of OH radicals which control the fluxes of ...

Peroxynitrite is a powerful and long-lived oxidant generated in vivo. Peroxynitrous acid (ONOOH), its protonated form, may penetrate into phospholipid bilayers and undergo homolytic cleavage to nitrogen dioxide (·NO2) and hydroxyl radicals (·OH), causing

The kinetics of the decay of gaseous peroxynitric acid
Chemical Physics Letters, 1978Abstract A kinetic study has been made of the thermal decay of HO 2 NO 2 using long path, FT IR spectroscopy. Mixtures containing HO 2 O 2 were prepared by the photolysis of Cl 2 , H 2 , and NO 2 in synthetic air (7000 torr). The observed decay law consisted of both first and second order components.

Ion-exchange chromatographic analysis of peroxynitric acid
Journal of Chromatography A, 2016Ion-exchange chromatographic analysis of peroxynitric acid (O2NOOH) was performed by combining an acidic eluate with an UV-vis detector and immersing the separation column in an ice-water bath. The decomposition behavior of peroxynitric acid in the solution was also studied using this system.

, 2014 Spectroscopic Characterization of Peroxynitrous Acid in cis-perp Configurations
The Journal of Physical Chemistry A, 2006This paper presents experimental evidence, supported by two-dimensional theoretical calculations, that HOONO can be observed in cis-perp (cp) configurations in a pulsed supersonic expansion. The spectral properties (transition frequency, rotational constants, and transition type) of OH overtone transitions originating from a state with predominately cp

Chemiluminescence characterisation of the reaction system Tb(III)–amino acid–peroxynitrous acid
Journal of Alloys and Compounds, 2008Abstract Chemiluminescence of the reaction system tryptophan–hydrogen peroxide–nitrite–Tb(III)–H2SO4 was used for the determination of tryptophan. The chemiluminescence intensity observed in the system tryptophan–hydrogen peroxide–nitrite–sulfuric acid, in the presence of Tb(III) ions was five times higher than that in a solution without Tb(III) ions.

On the Chemical and Electrochemical One-Electron Reduction of Peroxynitrous Acid
The Journal of Physical Chemistry A, 2005Peroxynitrous acid was reduced by cathodic linear sweep voltammetry at a gold electrode and by iodide at pH 3.2 and 5.6. The cathodic reduction wave was identified by measuring its decay in time, which was the same as observed by optical spectroscopy. The iodide oxidation was followed by optical measurement of the triiodide formation.
