抄録

Activated carbons surface-improved by different organic compounds were prepared and the adsorption characteristics of low-molecular weight organic compounds on these activated carbons were examined in gas and liquid phases. Methane and phenol served as adsorbates in gas phase and liquid phase adsorption, respectively. Pore volume and specific surface area of the activated carbons decreased by the introduction of acyl groups. Triphenylsilyl group introduction failed to decrease pore volume or specific surface area. In low-molecular weight organc compounds adsorption, the introduction of organic groups did not enhance the methane gas adsorptivity of the activated carbon. Phenol adsorptivity of activated carbon from aqueous solution increased as a result of increase in the hydrophobicity of the activated carbon surface due to organic group introduction.
