Overview

This analysis finds that corn-stalk biomass effectively removes cobalt ions in aqueous solutions, highlighting optimal adsorption conditions.

Key Points

  • Cobalt(II) ions were effectively removed from water using corn stalk biomass, enhancing water treatment methods.
  • The maximum adsorption capacity observed was 202.68 mg/g at an initial concentration of 250 mg/L.
  • Experiments revealed that optimal adsorption occurred at pH 9.1, with capacity peaks at 60 minutes of contact time.
  • These findings suggest that corn-stalk-derived carbon can significantly improve adsorption performance in water treatment applications.
