Reactivity of Chlorine Radicals (Cl• and Cl2•-) with Dissolved Organic Matter and the Formation of Chlorinated Byproducts.

Environmental Science and Technology, 2020
Chlorine radicals, including Cl• and Cl2•-, can be produced in sunlight waters (rivers, oceans, and lakes) or water treatment processes (e.g., electrochemical and advanced oxidation processes).

Dissolved Organic Matter

1996
Dissolved organic matter (DOM) is a complex mixture of organic compounds that is ubiquitous in terrestrial, aquatic, and atmospheric environments. Although it plays a key role in the global carbon cycle, it remains poorly characterized at the molecular-level because of its compositional heterogeneity and variability.

Removal of Dissolved Organic Matter by Anion Exchange: Effect of Dissolved Organic Matter Properties

Environmental Science & Technology, 2008
Ten isolates of aquatic dissolved organic matter (DOM) were evaluated to determine the effect that chemical properties of the DOM, such as charge density, aromaticity, and molecular weight, have on DOM removal by anion exchange. The DOM isolateswere characterized as terrestrial, microbial, or intermediate humic substances or transphilic acids.

Chromophoric dissolved organic matter in inland waters: Present knowledge and future challenges.

Science of the Total Environment, 2020
Chromophoric dissolved organic matter (CDOM) plays an important role in the biogeochemical cycle and energy flow of aquatic ecosystems. Thus, systematic and comprehensive understanding of CDOM dynamics is critically important for aquatic ecosystem ...

Cycling downwards – dissolved organic matter in soils

Soil Biology and Biochemistry, 2012
Dissolved organic matter has been recognized as mobile, thus crucial to translocation of metals, pollutants but also of nutrients in soil. We present a conceptual model of the vertical movement of dissolved organic matter with soil water, which deviates from the view of a chromatographic stripping along the flow path. It assumes temporal immobilization

Temperature Dependence of Dissolved Organic Matter Fluorescence

Environmental Science & Technology, 2018
The temperature dependence of organic matter fluorescence apparent quantum yields (Φf) was measured for a diverse set of organic matter isolates (i.e., marine aquatic, microbial aquatic, terrestrial aquatic, and soil) in aqueous solution and for whole water samples to determine apparent activation energies ( Ea) for radiationless decay processes of the

Chromophoric dissolved organic matter and dissolved organic carbon in Chesapeake Bay

Marine Chemistry, 2002
Chromophoric dissolved organic matter (CDOM) is the light absorbing fraction of dissolved organic carbon (DOC). The optical properties of CDOM potentially permit remote sensing of DOC and CDOM, and correction for CDOM absorption is essential for remote sensing of chlorophyll a (chl a) in coastal and estuarine waters.

Sulfurization of Dissolved Organic Matter Increases Hg–Sulfide–Dissolved Organic Matter Bioavailability to a Hg-Methylating Bacterium

Environmental Science & Technology, 2017
Reactions of dissolved organic matter (DOM) with aqueous sulfide (termed sulfurization) in anoxic environments can substantially increase DOM's reduced sulfur functional group content. Sulfurization may affect DOM-trace metal interactions, including complexation and metal-containing particle precipitation, aggregation, and dissolution.
