Abstract
The persistent water contaminants, especially the diclofenac sodium and Rhodamine B, severely concern human and marine life. Advanced and indigenous materials received greater attention in advanced remediation technologies. The study aims to synthesize a novel mesoporous nanocomposite (MSoGO@Bn) material using a facile and greener approach using Saccharum officinarum as a precursor of graphene oxide. Further, the bentonite-supported magnetite graphene oxide nanocomposite is utilized for efficiently remedying an aqueous solution contaminated with diclofenac sodium (DCF) and Rhodamine B (RhB). Advanced analytical techniques adequately characterize the nanocomposite material. The parametric studies viz pH, sorptive concentration, adsorption isotherm, and kinetics are extensively conducted and pointed the efficiency of MSoGO@Bn towards the DCF and RhB removal with the adsorption capacity of 55.02 and 12.68 mg/g, respectively. The organophilic interaction with π-π interaction bounds the DCF and RhB at the solid surface of MSoGO@Bn. Recovery and reusability revealed the stability of solid MSoGO@Bn. Additionally, the real matrix implication of solids indicated the more excellent selectivity of solids in removing these pollutants in the aqueous medium.
