General description
Humic acid (HA) is a heterogeneous macromolecule mainly found in soil and water.
Application
Humic acid has been used to prepare stock solution employed in the following experiments:
- Coagulation activity assay of Moringa oleifera protein extracts for humic acid removal.
- Adsorption edge experiment to study its effect on the sorption of tetracycline onto goethite.
- Evaluation of the ability of polymeric adsorbent Supelite Dax-8 to remove humic acid from nucleic acid extracts prior to quantitative real-time PCR (qPCR).

Recent studies suggest that direct mortality and physiological effects caused by pollutants are major contributing factors to global amphibian decline. However, even sublethal concentrations of pollutants could be harmful if they combined with other factors to cause high mortality in

Humic acid (HA) is composed of a complex supramolecular association and is produced by humification of organic matters in soil environments. HA not only improves soil fertility, but also stimulates plant growth. Although numerous bioactivities of HA have been reported

The retention of Cr(VI) in subsurface environment is highly dependent on humic acid (HA), however, the undissolved form is poorly investigated, the amount of which can be of two magnitude higher compared with the dissolved one in soils and sediments.
