The adsorption abilities of commercial activated carbon after thermal and chemical treatment were investigated. The chemical character of carbon surfaces was determined by applying the thermogravimetric method, measurement of adsorption isotherms of water vapor, and the process of neutralization of

✦ Synopsis
Two carbonaceous materials were synthesized by using the method of impregnation of mesoporous silicas obtained by applying the Pluronic copolymers as pore-creating agents. The isotherms of adsorption of methylene blue and methyl orange from aqueous solutions were measured by the static method. The profiles of adsorbate concentration change in time were obtained from the UV-vis spectra. The adsorption isotherms and kinetic dependence were discussed in the terms of theory of adsorption on heterogeneous surfaces.
