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 vapour 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.

Claims

exact text as granted — not AI-modified
We claim: 
     
         1 . An adsorbent for halogenated anaesthetics comprising:
 an inorganic material; and   an organic material providing a framework for the inorganic material.   
     
     
         2 . An adsorbent according to  claim 1  wherein the inorganic material is chromium. 
     
     
         3 . An adsorbent according to  claim 1  wherein the organic material is terephthalic acid. 
     
     
         4 . An adsorbent according to  claim 1  wherein the adsorbent can be substantially regenerated at approximately room temperature. 
     
     
         5 . An adsorbent according to  claim 1  wherein the adsorbent provides selectivity for sevofluorane in water vapour of approximately 1.0. 
     
     
         6 . An adsorbent according to  claim 1  wherein the inorganic material forms octahedral structures in the adsorbent. 
     
     
         7 . An adsorbent according to  claim 1  wherein the adsorbent comprises coordinatively unsaturated sites. 
     
     
         8 . A method of producing an adsorbent for halogenated anaesthetics comprising:
 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.   
     
     
         9 . An adsorbent for halogenated anaesthetics comprising:
 an aluminum-substituted mesoporous Santa Barbara amorphous (SBA-15) material.   
     
     
         10 . An adsorbent according to  claim 9  wherein the adsorbent is modified with Trimethoxy(propyl)silane.
