N2  - The implementation of inorganic adsorbents for the removal of heavy metals from industrial effluents generates secondary waste. Therefore, scientists and environmentalists are looking for environmentally friendly adsorbents isolated from biobased materials for the efficient removal of heavy metals from industrial effluents. This study aimed to fabricate and characterize an environmentally friendly composite bio-sorbent as an initiative toward greener environmental remediation technology. The properties of cellulose, chitosan, magnetite, and alginate were exploited to fabricate a composite hydrogel bead. The cross linking and encapsulation of cellulose, chitosan, alginate, and magnetite in hydrogel beads were successfully conducted through a facile method without any chemicals used during the synthesis. Energy-dispersive X-ray analysis verified the presence of element signals of N, Ca, and Fe on the surface of the composite bio-sorbents. The appearance and peakâ??s shifting at 3330â??3060 cmâ??1 in the Fourier transform infrared spectroscopy analysis of the composite celluloseâ??magnetiteâ??alginate, chitosanâ??magnetiteâ??alginate, and celluloseâ??chitosanâ??magnetiteâ??alginate suggested that there are overlaps of O-H and N-H and weak interaction of hydrogen bonding with the Fe3O4 particles. Material degradation,  mass loss, and thermal stability of the material and synthesized composite hydrogel beads were determined through thermogravimetric analysis. The onset temperature of the composite celluloseâ??magnetiteâ??alginate, chitosanâ??magnetiteâ??alginate, and celluloseâ??chitosanâ??magnetiteâ??alginate hydrogel beads were observed to be lower compared to raw-material cellulose and chitosan, which could be due to the formation of weak hydrogen bonding resulting from the addition of magnetite Fe3O4. The higher mass residual of celluloseâ??magnetiteâ??alginate (33.46), chitosanâ??magnetiteâ??alginate (37.09), and celluloseâ??chitosanâ??magnetiteâ??alginate (34.40) compared to cellulose (10.94) and chitosan (30.82) after degradation at a temperature of 700 °C shows that the synthesized composite hydrogel beads possess better thermal stability, owing to the addition of magnetite and the encapsulation in the alginate hydrogel beads. © 2023 by the authors.
