Carbon in Humic Fractions of Organic Matter in Soil Treated with Organic Composts under Mango Cultivation

Revista Brasileira de Ciência do Solo, 2016
Soil organic matter (SOM) plays a key role in maintaining the productivity of tropical soils, providing energy and substrate for the biological activity and modifying the physical and chemical characteristics that ensure the maintenance of soil quality ...

Humins from Biorefineries as Thermoreactive Macromolecular Systems [PDF]

ChemSusChem, 2018
AbstractConversion of lignocellulosic biomass often brings about the formation of several side products. Among these, a black and viscous coproduct known as humins is formed on acidic treatment of polysaccharides. To improve the efficiency of this process from an economical and environmental perspective, new solutions for humins valorization are ...

Mechanism of the Removal of AuCl Ions from Aqueous Solution by Means of Peat Soil Humin

Adsorption Science & Technology, 2011
Peat soil humin, obtained after the removal of fulvic and humic acid fractions according to the recommended procedure of the International Humic Substances Society (IHSS), has the ability to remove AuCl − 4 ions from aqueous solution.

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, EarlyView.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...

Lindane sorption and desorption behaviour on sediment organic matter [PDF]

Journal of the Serbian Chemical Society, 2013
The work is concerned with the sorption and desorption behaviour of lindane on four humic acid fractions (HAs) and two humin fractions, sequentially extracted from Ludas lake sediment.

Preparation of High‐Pressure Laminate With Bio‐Based Fructose‐HMF‐Amine Impregnation Resin

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
This study demonstrates the use of a resin made from renewable carbohydrates, free from phenol and formaldehyde, for impregnating recycled kraft paper to produce high‐pressure laminates. The resulting bio‐based laminate samples match the mechanical performance of conventional phenol‐formaldehyde‐based samples, highlighting their potential to replace ...

\u3csup\u3e13\u3c/sup\u3eC NMR Analysis of Biologically Produced Pyrene Residues by \u3cem\u3eMycobacterium\u3c/em\u3e sp. KMS in the Presence of Humic Acid [PDF]

, 2007
Cultures of the pyrene degrading Mycobacterium sp. KMS were incubated with [4-13C]pyrene or [4,5,9,10-14C]pyrene with and without a soil humic acid standard to characterize the chemical nature of the produced residues and evaluate the potential for ...

Dust Deposition and Loess Accretion in New Zealand's South Island: Examining Links between Cold‐Climate Processes and Dust Production

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
We compared temporal variability in dust and loess accretion in New Zealand's South Island with glacial activity in the central Southern Alps, considered the main mechanism of silt production, in (i) a proximal loess deposit at Barrhill, Rakaia River and (ii) a distal dust record from a peat mire in Central Otago.

Moisture effect on soil humus characteristics in a laboratory incubation experiment

Soil and Water Research, 2016
A 180-day laboratory incubation experiment (30°C) was conducted to investigate the quantitative and qualitative characteristics of humic fractions in a Mollisol at different moisture conditions.
