| Tartalmi kivonat: | In this study, we investigated the potential of biochar derived from corn harvest residues, modified with silicon, to enhance the removal efficiency of cadmium and lead ions from aqueous solutions. Our characterization of pristine and silicon-modified biochars using FourierTransform Infrared Spectroscopy (FTIR) confirmed the successful incorporation of silicon on the modified biochar's surface, a crucial factor for the enhanced adsorption of metals, especially Cd. The metal residue was quantified by Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES). Our adsorption experiments demonstrated that the silicon-modified biochar exhibited significantly improved adsorption capacity, achieving removal efficiencies exceeding 99% in various pH conditions. This high removal efficiency was achieved with a minimal amount of Si, and in combination with the use of a low-cost and widespread biochar precursor, this approach demonstrates its potential as a cost-effective strategy for the removal of metal contaminants from water. |
