Abstract

Adsorption of gallic acid with activated carbons have been investigated. Activated carbons differ in porous structure and chemical state of the surface. Regularities of adsorption process have been determined. The authors propose the mechanism of gallic acid adsorption. The use of activated carbons based on semi-coke to improve the quality of beer is proposed.

Keywords

Gallic acid, carbon adsorbents, adsorption
