Abstract
This investigation intended to the treatment of wastewater from cationic dyes utilizing economical eco-friendly 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.
