The Impact of Activated Carbon Oxidizing on the Adsorption of Fulvic Acids from Aqueous Solutions under Dynamic Conditions

摘要

The paper has investigated the adsorption of peat fulvic acids from aqueous neutral solutions on unoxidized and oxidized activated carbons under dynamic conditions. We have determined the share of biologically accessible organic carbon in the value of total organic carbon in the course of biofiltration. It has been shown that the generation of biologically accessible organic carbon on oxidized carbon begins earlier than on unoxidized one and results in a larger dynamic adsorption capacity of carbon in terms of fulvic acids.
