| Abstract Scope |
This study presents the physicochemical characterization and isothermal analysis of the adsorption capacity of Cu˛⁺, Ni˛⁺, and Zn˛⁺ in aqueous solutions using Activated Carbon (AC) derived from wood. Batch experiments were conducted to evaluate the effect of initial adsorbate concentration under controlled conditions. Characterization of AC included Point of Zero Charge (PZC), Fourier-Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), X-ray Diffraction (XRD), and Scanning Electron Microscopy with Energy-Dispersive Spectroscopy (HRSEM-EDS). Results confirmed a porous structure and the presence of oxygenated functional groups that enhance heavy metal interactions. Adsorption data showed strong agreement with the Freundlich isotherm model, indicating a heterogeneous surface and multilayer adsorption behavior. Correlation coefficients (R˛) were satisfactory for all metals, with Zn(II) showing the highest affinity (R˛ = 0.90), followed by Ni(II) and Cu(II), both with R˛ = 0.80. These findings support the potential of AC as an effective adsorbent for heavy metal removal in aqueous environments. |
