Preparation of fluorescent nanofibrous film as a sensing material and adsorbent for Cu2+ in aqueous solution via copolymerization and electrospinning

► Fluorescent nanofibrous film had high selectivity and sensitivity for Cu2+ ion. ► The nanofibrous film had high adsorption capacity for Cu2+ ion. ► Fluorescent nanofibrous film was prepared by electrospinning. ► The electrospun nanofiber material is used to detect and remove the Cu2+ for the first time.
