Overview

This investigation examines maize biomass parts' effectiveness in removing copper ions from water, indicating potential environmental applications.

Key Points

  • The study aims to evaluate how different parts of maize biomass can help remove copper ions from polluted water.
  • Evaluated maize biomass parts: seed chaff, stalk, cob, husk.
  • Measured adsorption capacity of each part for Cu2+ ions.
  • Used PIXE for characterization of maize husk.
  • Conducted FTIR analysis to assess functional groups involved in adsorption.
  • Examined surface structure using SEM imaging.
  • Husk had the highest adsorption capacity at 9.65 mg/g and 80.80% removal efficiency.
  • Adsorption capacity followed this order: husk > stalk > cob > seed chaff.
  • Maximum adsorption occurred within 45 minutes for all parts.
  • FTIR indicated complexation of Cu2+ ions with -OH groups in the husk.
  • SEM showed a multi-porous structure with uniform ion coverage on the husk surface.
