Investigation of the Potential of Repurposing Medium-Density Fiberboard Waste as an Adsorbent for Heavy Metal Ion Removal.

Medium-density fiberboard (MDF) waste generation has increased steadily over the past decades, and therefore, the investigation of novel methods to recycle this waste is very important. The potential of repurposing MDF waste as an adsorbent for the treatment of Cd(II), Cu(II), Pb(II), and Zn(II) ions in water was investigated using MDF offcuts. The highest adsorption potential in single-metal ion solution systems was observed for Pb(II) ions.

Adsorptive removal of Co(II) in aqueous solutions using clearing nut seed powder.

The present study assessed the potential use of clearing nut seed powder () as an adsorbent for the removal of Co(II) ions from aqueous solutions. Based on FTIR analysis, the adsorbent possesses hydroxyl, C-N, and C-O functional groups and SEM analysis indicated the presence of uneven porous surface structure, which is important for adsorption. Batch adsorption studies were performed to investigate the effect of contact time, initial pH, initial Co(II) concentration, adsorbent dosage, and temperature on adsorption.
