Comment on “A novel environmental-friendly nanobiocomposite synthesis by EDTA and Chitosan functionalized magnetic graphene oxide for high removal of Rhodamine B: Adsorption mechanism and separation property” [Chemosphere, 218 (2019) 715-725]

Abstract CS-EDTA-mGO nanobiocomposite was synthesized for the purpose of adsorbent and exhibited promising performances for the adsorption of Rhodamine B (RhB). The synthesized nanobiocomposite for RhB adsorption is commented and proposed in order to clarify the kinetics and mechanisms involved.
