STUDIES ON THE STRUCTURE OF HUMIC SUBSTANCES EXTRACTED FROM DIFFERENT SOILS [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2004 Humic and fulvic acids were extracted from normal (non-saune), saane, alkaline and newly reclaimed salt affected soils. These humic substances were characterized in terms of chemical composition.

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Al(III) and Fe(III) binding by humic substances in freshwaters, and implications for trace metal speciation. [PDF]
, 2002 Published experimental data for Al(III) and Fe(III) binding by fulvic and humic acids can be explained approximately by the Humic Ion-Binding Model VI. The model is based on conventional equilibrium reactions involving protons, metal aquo ions and their ...

Directed Synthesis of Humic and Fulvic Derivatives with Enhanced Antioxidant Properties
Agronomy, 2021 Redox moieties, which are present in the molecular backbone of humic substances (HS), govern their antioxidant properties. We hypothesized that a directed modification of the humic backbone via incorporation of redox moieties with known redox properties ...
