EEM fluorescence spectra of humic acids
Aim of this project was to compare structure differences in lignite humic acids and soil humic acids using EEM fluorescence spectroscopy. Soil humic acids were isolated from Haplic Chernozem (loca...

Influence of the modification of humic acids on their reactivity
Humic acids, as one of the most reactive part of soil, were modified by esterification of their carboxylic functional groups. Obtained methylated humic acids were mixed with non-modified humic acids

Study of lignitic humic acids by fluorescence spectroscopy.
Humic acids (HA) are the main components of humic substances. The content of low and higher molecular components of humic acids can be determined by fluorescence spectroscopy. Samples of humic

How Humic Acids Affect the Rheological and Transport Properties of Hydrogels
Humic acids are often regarded as substances with a supramolecular structure on the properties of widely-used hydrogel based on agarose after addition of humic acids–the protonated H-form of humic acid...
