A fluorescent magnetic chitosan-based hydrogel (FMCH) incorporating Amino-Functionalized Fe3O4 nano-particles (AF-Fe3O4 NPs) and cellulose nanofibers (CNFs) modified with carbon dots (CDs) was successfully synthesized via the crosslinking method. The FMCH was used as an adsorbent for removing Cr (VI) from aqueous solution and it exhibited encouraging adsorption performance for Cr (VI). The composition and structure of FMCH were characterized and its Cr (VI) sorption performance was evaluated. The results demonstrated that this hydrogel had 3D porous structures and a higher adsorption ability o...
