REMOVAL/CONCENTRATION METHOD OF CARBON MONOXIDE AND ANALYSIS DEVICE OF TRACE CARBON MONOXIDE

摘要

PROBLEM TO BE SOLVED: To provide a removal/concentration method of carbon monoxide capable of concentrating carbon monoxide in a reusable form in addition to perform removal and concentration at low cost, and provide an analysis device of trace carbon monoxide capable of measuring carbon monoxide of low concentration. SOLUTION: This method is to remove or concentrate carbon monoxide utilizing characteristic of hemoglobin selectively and chemically bonding with carbon monoxide, and in a view from the liquid side or the gas side containing carbon monoxide, carbon monoxide is removed, in a view from the hemoglobin side chemically bonded with carbon monoxide, carbon monoxide is concentrated. When carbon monoxide is contacted with hemoglobin (a), oxygen bonded with hemoglobin is substituted by carbon monoxide so as to chemically bond with hemoglobin (b), and hence removal and concentration of carbon monoxide is performed. By chemically reacting hemoglobin chemically bonded with the carbon monoxide, concentrated carbon monoxide can be taken out of the hemoglobin (c).
