METHOD OF ADSORBING AND METHOD OF RECOVERING FLUORINE-CONTAINING COMPOUND

摘要

An adsorption process in which high adsorption of C2-C6 fluorine-containing compound can be attained without any morphological change thereof by the use of active carbon; and a desorption process in which active carbon and adsorbed substances can be recycled by desorption from active carbon. A liquid containing the C2-C6 fluorine-containing compound is brought into contact with active carbon to thereby cause the active carbon to adsorb the fluorine-containing compound and thus obtain a liquid of low fluorine-containing compound content. The active carbon having the adsorbed fluorine-containing compound is heated so as to desorb the fluorine-containing compound from the active carbon.
