dc.description.abstract | The current study, novel magnetic nano-composite particles (Fe3O4@EPS) were successfully synthesized via the co-precipitation of iron (III) chloride and iron (II) sulfate (Fe3O4 nanoparticles) with exopolysaccharides (EPS) derived from the microalga Chlorella vulgaris. The physico-chemical nature of the Fe3O4@EPS was investigated in depth. Transmission electron microscopy (TEM) results estimated the core-shell nature of Fe3O4@EPS aggregated inside the indistinctly layered EPS matrix to be 10-20 nm in size. Scanning electron microscopy-based energy dispersive spectral analysis indicated that elemental Fewas successfully loaded on to the EPS polymeric ion-exchanger at a rate of 63.3% by weight. FT-IR results demonstrated that Fe3O4 nanoparticles were successfully modified by the functional groups present in EPS. Fe3O4@EPS showed a highly magnetic nature at 5.0 emu/g. The XPS survey spectrum, which showed two major peaks at 724.1 and 710.2 eV revealed the elemental composition and electronic structure of Fe3O4 nanoparticles and Fe3O4@EPS. Furthermore, nutrient removal from wastewater was studied. Under optimum conditions (3.5 g/L of Fe3O4@EPS, pH 7.0 and 13 h of incubation) 91% of PO43- and 85% of NH4+ were effectively eliminated. These findings demonstrate the potential of Fe3O4@EPS for removing PO43- and NH4+ in wastewater treatment plants. (C) 2020 Published by Elsevier B.V. | - |
