Spectroscopic characterization of the structural and functional properties of natural organic matter fractions
TL;DR: Results of these spectroscopic studies confirm the heterogeneous nature of NOM, and point out the importance of isolation and improved characterization of various NOM subcomponents in order to better understand the behavior and roles of Nom in the natural environment.
Journal ArticleDOI
Proton-binding study of standard and reference fulvic acids, humic acids, and natural organic matter
TL;DR: In this paper, the acid-base properties of 14 standard and reference materials from the International Humic Substances Society (IHSS) were investigated by potentiometric titration.

Chapter 1 Humic Substances: Chemistry and Reactions
TL;DR: Humic substances are major organic constituents of soils and sediments and are widely distributed over Earth's surface, occurring in almost all terrestrial and aquatic environments as discussed by the authors, and Humic substances arise from the chemical and biological degradation of plant and animal residues and from synthetic activities of microorganisms.
