Overview

Lab-synthesized and commercial mineral adsorbents effectively removed cobalt and copper from water, suggesting practical applications for environmental cleanup.

Key Points

  • Evaluate the effectiveness of various mineral adsorbents in removing Co(II) and Cu(II) from aqueous solutions.
  • Conducted batch experiments using lab-synthesized HAP, magnetite, and LDHs for heavy metal uptake.
  • Used XRD and XPS techniques to analyze the structural characteristics and adsorption mechanisms of the adsorbents.
  • Tested both commercial and synthesized adsorbents for comparative analyses.
  • Synthesized HAP achieved 98.10% Co(II) and 99.35% Cu(II) removal rates.
  • Ca-Al-Cl LDH showed the highest Co(II) removal at 99.756% and synthesized HAP had the highest Cu(II) removal at 99.995%.
  • Commercial magnetite's performance was significantly dosage-dependent, requiring 1 g to reach near-complete removal.
