This paper presents adsorption isotherms and desorption data of isoflurane from a carrier gas (nitrogen) on different adsorbents at 25 degrees C and 1 bar. As adsorbents activated carbons, newly developed carbon adsorbents and dealuminated zeolites were used. The adsorption of isoflurane was studied in trace level concentrations up to 1200 ppm(V). Common isotherm equations were fitted to the measured data. The adsorption isotherms show distinctly different capacities depending on the polarity and the pore structure of the adsorbent. The investigation of desorption reveals weak physical interactions between isoflurane and the surface of most adsorbents.
