| description | In this paper commercially available activated WD-extra carbon (Gryfskand) which is applied for water treatment was used. Activted carbon was modified by the following chemical agents: H2O2, HNO3 and HCl. The textural characteristics of the samples were determined by the analysis of physical adsorption isotherms of nitrogen vapor at 77 K. The Boehm titration general procedure was used to determine the distribution of the surface functional groups. Chemical modifications significantly affect the chemical, structural and surface properties of activated carbons. Hydrophobization with ethereal stearic acid was performed on the raw material and samples after chemical modification. Hydrophobic properties of the samples were specified. The relationship of the chemical modification agents with hydrophobization degree was indicated. |
