Abstract Supercritical fluid CO2 extraction of the live, dried algaPilayella littoralis efficiently removes non-humic substances in hours instead of the days required for sequential extraction with ether, acetone, ethanol and dioxane. Completion of extraction (including aqueous removal of alginic acids) with either preliminary in a standard procedure gives humic acid samples with closely comparable properties.
