Activation of Waste Materials with Carbon(IV) Oxide as an Effective Method of Obtaining Biochars of Attractive Sorption Properties towards Liquid and Gas Pollutants

Activation of Waste Materials with Carbon(IV) Oxide as an Effective Method of Obtaining Biochars of Attractive Sorption Properties towards Liquid and Gas Pollutants

Biochars that are the subjects of this report have been obtained from the residue of supercritical extraction of common nettle seeds with CO<sub>2</sub>. The residue was subjected to direct activation with carbon(IV) oxide as an activator. The obtained biochars were found to have a speci...
