There is provided a selective fixing agent capable of facilitating the decomposition treatment of only a halogenated aromatic compound. A cyclodextrin is dispersed in an organic solvent, an organic dibasic acid or an organic dibasic acid halide-containing organic solvent is added dropwise, the reaction solution is stirred at a temperature of 50 to 100 ° C., and then the reaction solution is added. A method for producing a porous cyclodextrin polymer, comprising dropwise adding alcohols, aryl alcohols, or phenols to an esterification reaction at a temperature of 0 to 10 ° C. A selective fixing agent for a halogenated aromatic compound contained in an organic medium, comprising the porous cyclodextrin polymer. [Selection] Figure 1 |
