Abstract
The adsorption of CH2Cl2, CH3Cl, CCl4, and H2O vapors on the surface of multi-walled carbon nanotubes and alumina in the temperature range of 10—25 °C was studied. Dependences of the isosteric heat of adsorption on the surface coverage were plotted. The initial heat of adsorption of dichloromethane, chloroform, and CCl4 on Al2O3 was found to be equal to 71, 28, and 31 kJ mol–1, respectively. In most cases, adsorption on the oxide adsorbent was characterized by a higher heat of adsorption compared to that found on the carbon material, which is apparently related to chemical interaction of sorbed molecules with the OH groups of the alumina surface.
