Abstract
In order to handle the toxic pollutants associated with heavy metal and agriculture wastes, researchers have attempted to develop several adsorbent materials with change of shape, size, architecture, surface charges, and surface biomolecules. Therefore, with a view of enhancing the efficiency of adsorbent materials, the present study deals with cobalt spinel ferrite (CoFe2O4) incorporated nanoporous carbon (NC) derived from palm kernel shell waste towards Hg(II) adsorption. The composite formed by the hydrothermal method was characterized thoroughly with FESEM, XRD, FTIR, pore sizes, and thermal analysis. Further, the Hg(II) adsorption studies were tested looking the effect variation of solution pH, dose, initial concentration, and contact time of adsorbent. Also, kinetic research (Freundlich model) exhibited finest adsorption isotherm having maximum Hg(II) sorption efficacy around 232.56 mg/g. Additionally, the thermodynamic studies based on ΔG, ΔH, and ΔS values confirmed the adsorption to be spontaneous, favorable, and endothermic reaction. Moreover, the adsorption effectiveness of the NC@CoFe2O4 nanocomposite was assessed using an actual sample of condensate from the oil and gas industry, demonstrating a remarkable 93% removal rate for Hg(II) ions in wastewater. Therefore, based on the results, the synthesized NC@CoFe2O4 nanocomposite can serve as a promising candidate for wastewater treatment considering its efficiency, inexpensive, and environmentally friendly source.
