Agarose Hydrogels Enriched by Humic Acids as the Complexation Agent
(MDPI, 2020-03-19)
The transport properties of agarose hydrogels enriched by humic acids were studied. Methylene blue, rhodamine 6G and Cu(II) ions were incorporated into hydrogel as diffusion probes, and then their release into water was ...
Comparative Study of Binding Behaviour of Cu(II) with Humic Acid and Simple Organic Compounds by Ultrasound Spectrometry
(Bentham Science Publihers, 2011-11-12)
Several simple organic (hydroxy)acids as models of principal functional moieties of humic acids and the
copper ion as a model ion were used to investigate the metal-humic interactions. The quantum chemical calculations ...
Complexation of Copper(II) with Humic Acids Studied by Ultrasound Spectrometry
(Hindawi Publishing Corporation, 2012-05-14)
Copper biogeochemistry is controlled by bonding to natural organic matter. The soluble forms of bonded copper can be more
biologically active due to the higher migration in environmental systems and instability of some ...
How Humic Acids Affect the Rheological and Transport Properties of Hydrogels
(MDPI, 2019-04-19)
Huminové kyseliny jsou považovány za látky s tzv. supramolekulární strukturou, jež je základem jejich unikátních vlastností a fungování v přírodě. Naše studie potvrdila, že již malý přídavek těchto látek do agarozových ...
New possibility for characterization of dissociation behaviour of supramolecular electrolytes: results obtained for the International Humic Substances Society standard and reference samples by coulometry
(Springer, 2021-06-24)
Background: Humic substances can be considered as polyelectrolytes with supramolecular character and complicated behaviour in water environment. The fractions of humic substances dissolved in water are the most active ones ...
