Overview

Novel adsorbent removes Cr (VI) and methyl orange in water, demonstrating efficient environmental remediation.

Key Points

  • This research aims to enhance the removal of chromium (VI) and methyl orange pollutants using a novel magnetic chitosan composite.
  • Synthesized magnetic chitosan composite by integrating chitosan with UiO-66-NH2 MOF and Fe3O4.
  • Investigated effects of pH, adsorbate concentration, contact time, and temperature on adsorption performance.
  • Characterized the adsorbent using various techniques for surface area, functional groups, and chemical state.
  • Achieved equilibrium adsorption capacity of 149.25 mg/g for methyl orange and 169.49 mg/g for Cr (VI) at optimal pH.
  • Adsorption data aligned with the Langmuir model, indicating strong chemical interactions.
  • Maintained over 70% removal efficiency for both pollutants after four cycles of use.
