Waste shrimp shell mediated Chitosan-Magnesium Oxide nanocomposite: Synthesis, characterization and exploitation towards acenaphthene removal from aqueous solution

Keeping the sustainability concept in view, a green, biocompatible, eco-friendly, and advantageous nano-composite was fabricated by impregnation of chitosan derived from waste shrimp shells onto Magnesium oxide nanoparticle (MgO) for exploiting in acenaphthene (ACN) removal from wastewater resources. The tested nanocomposite showed a high potential for ACN adsorption at pH 5.5. The thermodynamic evaluations laid the spontaneity nature of the process (∆G ≤-25.93 kjmol −1 ) bearing a ∆H value of 12.701 kjmol −1 which shows a favorable physisorption phenomenon. Kinetic evaluations demonstrated that the studied adsorption system conforms to pseudo-first order model to a greater extent. Other kinetic evaluations…
