Abstract (en)

[origin: WO2021133332A2] The present invention relates to a cross-linked composite membrane developed to be used for selectively separating cationic organic compounds from an aqueous solution comprising cationic and anionic organic compounds, and to a method for preparing said composite membrane. The inventive composite membrane comprises cross-linked nanofibers and has a water- insoluble, flexible, and pliable (bendable) structure. The inventive composite membrane is used as a filter for selectively separating cationic organic compounds from an aqueous solution comprising cationic and anionic organic compounds.
