Production of high-performance lead(II) ions adsorbents from pea peels waste as a sustainable resource

This research deals with a highly efficient, selective, low-cost, and recyclable adsorbent for the fast removal of lead (Pb)(II) ions from aqueous solutions, and an investigation of the related adsorption mechanisms. Three types of materials were prepared from pea peels waste using simple, energy-ef...

520 |a This research deals with a highly efficient, selective, low-cost, and recyclable adsorbent for the fast removal of lead (Pb)(II) ions from aqueous solutions, and an investigation of the related adsorption mechanisms. Three types of materials were prepared from pea peels waste using simple, energy-efficient and environmentally friendly treatment. Obtained adsorbents were characterized by elemental analysis, infrared spectroscopy, scanning electron microscopy, Boehm titration, and the main parameters were determined. The highest adsorption capacity was observed for the biochar prepared by heating of pea peels at 600°C for 30 minutes. The uptake of Pb(II) ions on pea peels-derived samples was examined as a function of pH, contact time, and initial Pb2+ concentration. Obtained results from adsorption experiments of Pb(II) ions on the biochar surface indicate high adsorption capacity, and the possibility of its preconcentration and selective removal in the presence of zinc(II) and cadmium(II) ions. This confirms a potential application of such materials in water remediation
