Abstract
  • Physical adsorption of phenol on graphite is studied through canonical (CEMC) and grand canonical(GCMC) ensembles Monte Carlo computer simulations in a wide temperature range. Adsorbate−adsorbentinteractions are modeled by employing the well-known potential developed by Steele. Adsorbate−adsorbateinteractions include dispersion and electrostatic interactions. Phenol's dipole moment is modeled by placingpartial charges over all the atoms of the molecule calculated with AM1 method using 34 orbitals. The effectof electrostatic interactions upon the adsorption process and adsorbed film structure will be discussed.Several features of the gas−solid and gas−gas interaction potentials will be presented. Phenol cross-sectional area is evaluated at different temperatures. The structure of the adsorbed phase is also investigated.
