摘要：
This investigation intended to the treatment of wastewater from cationic dyes utilizing economical ecofriendly nanocomposites arranged by green strategy. For this reason, Graphene oxide was set up and trapped in Arginine/Chitosan (Arg/Cs) hydrogel to perform Arg/Cs/GO nanocomposite. The magnetic nanocomposite Arg/Cs/GO-mag additionally arranged in situ to be receptive to a magnetic field. Characterization of Arg/Cs/GO, and Arg/Cs/GO-mag was performed. The impacts of different working conditions like starting pH, connect time, and starting dye dose on the sorption of methylthioninium chloride (MB) have been researched and pseudo-second order formula demonstrated much portrayed the sorption of MB. The thermodynamic variables were ascertained to anticipate the sorption kind. (C) 2018 Hosting by Elsevier B.V.
