The adsorption of volatile organic compounds (VOCs) on activated carbon, silica gel, and type 13X synthetic zeolite was measured by the method of gravimetric adsorption. The selected VOCs were oxygenated hydrocarbons including methyl acetate, ethyl acetate, propyl acetate, butyl acetate, isopropyl acetate, and isobutyl acetate. The equilibrium isotherm data of this study were fitted by the Freundlich and Langmuir equations. The average values of R-2 when using the Freundlich and Langmuir equations to fit the equilibrium isotherms are 0.99 and 0.96, respectively. The results demonstrate that both the Freundlich and Langmuir equations are adequate for fitting the adsorption data of oxygenated hydrocarbons onto the activated carbon, silica gel, and 13X zeolite.
