SOIL NITRATES

Marine Light Alkyl Nitrates

In the usual photoionization process, the absorption and emission of photons between the light field and the photoexcited electron packet is an arbitrary process that broadens the energy distribution of the electrons. However, there is no net exchange of energy between the two, and the drift velocity of the electron packet is unchanged. Kienberger et al. (p. 1144; see the Perspective by Lewenst...

Determination of nitrates in plasma.

Because of the high efficacy of existing nitrates, alternative dosage formulations have been developed rather than new compounds. These new formulations challenge the analyst to develop analytical methods with lower sensitivity and higher precision. Isosorbide dinitrate is analysed in the presence of its major metabolites isosorbide 2-mononitrate and isosorbide 5-mononitrate. The present method...

Microbial degradation of glycerol nitrates.

The fate of glycerol trinitrate when exposed to microbial attack has been investigated. Contrary to some earlier reports, this compound was readily biodegraded by employing batch or continuous techniques under a variety of cultural conditions. Breakdown of glycerol trinitrate took place stepwise via the dinitrate and mononitrate isomers, with each succeeding step proceeding at a slower rate. Af...
