This study investigated the production and characterization of activated carbon from discarded wooden pallets (CP). The charcoal produced had an active area of 715.94 m².g-1 and a high oxalic acid adsorption capacity of 5.66 x 10⁻³ mol.g-1. Comparisons with common adsorbent materials such as tamarind seed charcoal, green coconut shell and commercial pine activated carbon showed that CP is competitive in terms of adsorption efficiency. The Freundlich isotherm was identified as the most appropriate to describe the CP adsorption behavior, with a high correlation (0.9902), indicating a heterogeneous adsorption surface. The results highlight the feasibility of using CP as an effective and sustainable adsorbent, taking advantage of discarded materials, for industrial and environmental applications, such as removing pollutants from aqueous solutions.
