METHOD FOR SELECTIVELY FIXING PERSISTENT ORGANIC POLLUTANT USING CYCLODEXTRIN POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for selectively fixing POPs contained in a liquid medium or adhered to a solid substance and removing the POPs with high efficiency using a cyclodextrin polymer.SOLUTION: There is provided a method which comprises the steps of: washing a liquid medium containing persistent organic pollutants or a solid substance to which persistent organic pollutants are adhered with a low-polar organic solvent; and bringing a polymer produced by condensing cyclodextrin with an organic dibasic acid or a halogenated organic dibasic acid, which optionally is a cyclodextrin polymer which may have an alkyl group or an aryl group at its terminal, into contact with the low-polar organic solvent that is used in the washing step to selectively fix the persistent organic pollutants to the cyclodextrin polymer.
