The role of nitrogen in chromophoric and fluorescent dissolved organic matter formation

Marine Chemistry, 2007
Abstract Microbial and photochemical processes affect chromophoric dissolved organic matter (CDOM) dynamics in the ocean. Some evidence suggests that dissolved nitrogen plays a role in CDOM formation, although this has received little systematic attention in marine ecosystems.

Fluorescence‐based proxies for lignin in freshwater dissolved organic matter

Journal of Geophysical Research: Biogeosciences, 2009
Lignin phenols have proven to be powerful biomarkers in environmental studies; however, the complexity of lignin analysis limits the number of samples and thus spatial and temporal resolution in any given study. In contrast, spectrophotometric characterization of dissolved organic matter (DOM) is rapid, noninvasive, relatively inexpensive, requires ...

[Effect of spectra correction on the fluorescence characteristics of dissolved organic matter].

Guang pu xue yu guang pu fen xi = Guang pu, 2014
The Excitation-emission matrix (EEM) fluorescence spectra of dissolved organic matter (DOM) are not only dependent on the chemical structure of DOM as well as the local chemical environment around the DOM, but also dependent on the instrument employed for the analysis.

[Fluorescence characterization of dissolved organic matter in East China sea].

Guang pu xue yu guang pu fen xi = Guang pu, 2010
Sea water samples were collected in the East China Sea in March and April, 2005, and three-dimensional fluorescence of dissolved organic matter was measured by fluorescence excitation-emission matrix spectroscopy. The position, number and intensity of fluorescence peak in the spectra and the relations of the peaks were analyzed to determine the type ...
