Spectrophotometric determination of sodium azide
The Analyst, 1985An established spectrophotometric method was employed to determine the concentration of sodium azide. It was found that this method could only be used with a good accuracy (to within ±0.3%) under the following conditions: the solution of cerium(IV) ammonium nitrate, which was prepared using analytical-reagent grade materials without further ...

Sodium Azide Burn: A Case Report
Journal of Burn Care & Rehabilitation, 2001Chemical burn injuries commonly occur at the workplace and can be caused by a variety of agents. Sodium azide is a volatile compound used in the industrial setting and it is also a constituent of car airbags. The known toxic effects of sodium azide include hypotension, bradycardia, and headaches.

Kinetics of the Photolysis of Sodium Azide
The Journal of Chemical Physics, 1961The evolution of N2 from solid NaN3 during photolysis is shown to result from active sites located as deep as a few hundred lattice constants within the crystallites. These active sites diffuse to the free surface to produce N2, exhibiting a diffusion constant ∼10—15 cm2/sec.

Laser-induced decomposition of sodium azide
Journal of Electron Spectroscopy and Related Phenomena, 1983Abstract The decomposition of sodium azide, NaN3, has been studied using a pulsed carbon dioxide laser. Chemiluminescence associated with the decomposition has been measured with and, without, the azide surface in the detector field of view. Near the decomposition threshold, emission has been observed in the wings of the Na 3p → 3s transition at 589 ...

The thermal behaviour of sodium azide in zeolites
Thermochimica Acta, 1995Abstract Upon thermal treatment, NaN3-doped zeolite transforms stepwise. After endothermic dehydration, the NaN3 decomposes exothermically in air and under N2 flow. The temperature of decomposition is higher than that of the pure azide. Part of the sodium azide remains intact up to 1000 K. The process was also monitored by IR spectroscopy.

Lattice Dynamics of Rhombohedral Sodium Azide
The Journal of Chemical Physics, 1972The external vibrational modes of rhombohedral NaN3 have been studied by means of normal mode calculations and inelastic neutron scattering measurements on powder samples. Phonon dispersion curves and displacement weighted frequency distributions have been computed using force-constant models in which the coupling parameters are determined by fitting ...

Acute neurotoxicity of sodium azide and nitric oxide*1
Fundamental and Applied Toxicology, 1991Sodium azide is a chemical of rapidly growing commercial importance with a high acute toxicity and an unknown mechanism of action. Although it has some chemical properties and biological effects in common with cyanide, its lethality does not appear to be due to inhibition of cytochrome oxidase. Unlike cyanide it is a potent vasodilator and inhibitor of

Inactivation of lignin peroxidase by phenylhydrazine and sodium azide
Archives of Biochemistry and Biophysics, 1990Lignin peroxidase (LiP) is rapidly inactivated in a concentration-dependent manner by H2O2 and either phenylhydrazine or sodium azide. Full inactivation of isozyme 2b (H8) requires approximately 50 eq of phenylhydrazine or 80 eq of sodium azide. Anaerobic incubation of isozyme 2b with [14C]phenylhydrazine and H2O2 results in 77% loss of catalytic ...

Multiple Poisonings with Sodium Azide at a Local Restaurant
The Journal of Emergency Medicine, 2014Sodium azide is a chemical with a mechanism similar to cyanide. There is concern that it could be used as a chemical warfare agent.We report a cluster of poisonings that occurred at a public restaurant and the subsequent investigation that identified iced tea contaminated with sodium azide (NaN3) and hydrazoic acid, as the foodborne vehicle and agents,
