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 ...
How the Supramolecular Nature of Lignohumate Affects Its Diffusion in Agarose Hydrogel
(MDPI, 2020-12-10)
Lignohumate, as an industrially produced analog of natural humic substances, is studied from the point of view of its diffusion properties. This work focuses on its permeation ability, important in agricultural and ...
The Effect of Supramolecular Humic Acids on the Diffusivity of Metal Ions in Agarose Hydrogel
(MDPI, 2022-02-02)
Humic acids are known as natural substances of a supramolecular nature. Their self-assembly ability can affect the migration of heavy metals and other pollutants in nature. The formation of metal-humic complexes can decrease ...
Diffusion of dyes in polyelectrolyte-surfactant hydrogels
(Royal Society of Chemistry, 2022-04-25)
In this work, hydrogels formed by interaction of biopolymeric electrolytes and oppositely charged surfactants are studied from the point of view of their ability to incorporate model hydrophobic dyes in their micelle-like ...
How the Addition of Chitosan Affects the Transport and Rheological Properties of Agarose Hydrogels
(MDPI, 2023-01-23)
Agarose hydrogels enriched by chitosan were studied from a point of view diffusion and the immobilization of metal ions. Copper was used as a model metal with a high affinity to chitosan. The influence of interactions ...
Effect of Chitosan as Active Bio-colloidal Constituent on the Diffusion of Dyes in Agarose Hydrogel
(MDPI, 2023-05-09)
Agarose hydrogel was enriched by chitosan as an active substance for the interactions with dyes. Direct blue 1, Sirius red F3B, and Reactive blue 49 were chosen as representative dyes for the study of the effect of their ...
