Adsorption of a pyridine-phenol mixture from aqueous solutions with preheated active carbons

Abstract

Abstract The article investigates the fundamental possibility of using preheating of the activated carbon in air and in an inert atmosphere to increase its adsorption capacity during adsorption extraction from aqueous solutions of a mixture of phenol – pyridine. It is found that such a modification affects more adsorption of pyridine than of phenol. At the same time, heating in an inert atmosphere turned out to be more efficient.
