Abstract: An adsorbent for halogenated anaesthetics includes: an inorganic material; and an organic material providing a framework for the inorganic material. The inorganic material may be chromium and the organic material may be terephthalic acid. The adsorbent may be formed or configured such that the adsorbent includes coordinatively unsaturated sites or such that the inorganic material may form octahedral structures. The adsorbent is formed or configured to be substantially regenerated at approximately room temperature and to provide selectivity for sevofluorane in water vapor of approximately 1.0. A method of producing an adsorbent includes: selecting an appropriate chemical containing an inorganic material; selecting an organic material to provide a framework for the inorganic material; dissolving the base chemical in water; mixing the organic material with the dissolved base chemical; heating the mixture; filtering the mixture to remove excess organic material; and drying the filtrate.

Abstract: A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.
