Fatty acids promote fulvic acid intercalation by montmorillonite
Applied Clay Science, 2014Abstract Organic matter (OM) adsorbed to the interlamellar surfaces of swelling clay minerals is particularly stable, with residence times as long as 2000 to 10,000 years. Intercalation of OM by smectitic clay minerals may therefore increase the stable C reservoir in both soils and sediments.

Fulvic acid composition in degraded fenlands
Journal of Plant Nutrition and Soil Science, 2001Fulvic acids (FAs) from topsoil and ground water solutions were investigated to discover effects of land use and peat degradation on their molecular chemical composition and thermal properties. The FAs were extracted from three Gleysols under arable land, intensive and extensive grassland, and from three Histosols under alder forest, extensive ...

Interactions between montmorillonite and fulvic acid
Geoderma, 1976Abstract The isotherms at 20°C for the adsorption of 14 C-labelled fulvic acid from aqueous solutions by montmorillonite containing different exchangeable cations, have been determined. Below a concentration of 0.45 mg/ml and at near neutral pH, all samples give linear isotherms, the slope of which increases in the order Ba 2+ 2+ 2+ 3+ 3 ...

Aliphatic structures in peat fulvic acids
Science of The Total Environment, 1987Abstract Fulvic acids, extracted from strongly humified milled peat, were studied through 13C-NMR measurements and cupric oxide oxidations. The 13C-NMR spectrum shows signals caused by the carboxylic carbons, aromatic or olefinic carbons, acetal carbons, aliphatic alcohol carbons and methylene and methyl carbons.

Physico-Chemical Properties of Fulvic Acids
2003By means of extraction and ion exchange rulvic acids with variable vestigial content of metals were separated from bottom sediments. These acids were subject to a physico-chemical analysis, which evaluated their electrokinetic potential, the size of molecules, absorbance, electrical conductivity of the solution as well as the relation of these factors ...

Determination of fulvic acids in water
Journal of Applied Chemistry, 1959AbstractA method for the determination of fulvic acids present in naturally‐occurring waters has been developed, based on the measurement of the ultra‐violet absorption spectrum of the sample. The method has been applied to samples of water from different parts of the country, and the results indicate that for moorland waters the fulvic acids are very ...
