Adsorption of peat fulvic acids from neutral aqueous solutions on non-oxidized and oxidized active carbon with and without hydrogen peroxide was investigated. Influence of surface groups of active carbon (АС) on equilibrium adsorption of fulvic acids from aqueous solutions was estimated. It was shown that fulvic acids adsorption efficiency has been advanced by ~ 49% with the replacement of non-oxidized carbon to oxidized one.

Keywords: active carbon, fulvic acids, oxidized carbon, adsorption equilibrium, redox potential.
