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).
