Oxidized Activated Carbon

Activated carbon made by clean coal and 25% coconut shell was selected to be modified with different concentrations’ HNO3. The productions were characterized by BET, XPS, FTIR and the moisture adsorption of performance is investigated by the DVSA-STD dynamic vapor analyzer. The results show that specific surface area of the activated carbon modified by the 10% concentration of HNO3 is improved 1.3 times than the unmodified one. By comparison the higher concentrations of HNO3 have weaker effects on the specific area of activated carbon. The water vapor adsorption capacity of activated carbon modified by HNO3 at 10% concentration is 1.5 times higher than the unmodified at room temperature at30% RH.
