Abstract
The surface of waste wool rich carpet was modified to enable recycling as an adsorbent material to remove pollutants from water and to avoid bulky carpets contributing to landfill. The proteins of the wool fibres in waste carpets adsorbed either copper(II) nitrate or iron(II) ions to form nanoparticles of Hydrated Ferric Oxide (HFO). The copper(II) ions reversibly bound to the wool carpet. The strongest binding of the nanoparticles of HFO occurred after first oxidizing the surface epicuticle layer of the wool fibres and this binding was studied by FTIR and SEM. In a batch anion exchange process the HFO supported on oxidized carpet efficiently adsorbed phosphate. The phosphate bound to HFO was subsequently recovered by anion exchange via washing with an alkaline sodium chloride solution.
