Abstract

The work demonstrates a new greener approach in developing bio-composite magnetic nanoparticles (Fe3O4@PBP) containing a sorbent extracted from papaya (Carica papaya) bark for efficient uranium (VI) sorption from aqueous media. The findings showed that Fe3O4@PBP nano composites exhibited a characteristic average size of around 26.4 nm, as inferred from the XRD data. Further, these nano composite performed well in the uptake of uranium (VI), revealing the removal efficiency and the maximum adsorption capacity to be 88.8% and 120.48 mg/g, respectively. The thermodynamic investigation indicated that the endothermic uranium(VI) uptake sorption process by expeditious Fe3O4@PBP nano composite is naturally impulsive.
