The present invention relates to a method comprising washing a liquid medium containing persistent organic pollutants or a solid substance having persistent organic pollut - ants adhered thereon with low-polar a organic solvent, and then bringing a cyclodextrin polymer into contact with the low-polar or- ganic solvent that is used in the aforementioned washing procedure to thererby fix the persistent organic pollutants onto the cyclo - dextrin polymer selectively, wherein the cyclodextrin polymer is produced by condensing cyclodextrin with an organic dibasic acid ® or a halogenated organic dibasic acid and may have an alkyl group or an aryl group at a terminal thereof. § (57)^: V<7 Px + X h U >/K'J \"7 — LT, I I-l£ n fooT, Pf+X
