The removal of Congo red (CR) from the aqueous solution was reported in this work using zeolitic imidazolate framework-8/graphene oxide/magnetic chitosan (ZIF-8-GMCS) composite as a novel bio-adsorbent. Such the ZIF-8-GMCS...
Graphene/chitosan-based hydrogel was synthesized using glutaraldehyde as crosslinking agent in room temperature and it used for removal of Congo red dye from aqueous solution.
