This study developed a new analytical method using Molecular Absorption Spectroscopy (MAS) to track the ion cover in adsorption solution per peel (mesocarp) of Baru (Dipteryx alata). The adsorption study was conducted at different pH and contact time (kinetic), encountering 4.0 as the best pH for adsorption experimental conditions. The variation of contact time showed a pseudo-second-order adsorption kinetic behavior. The interpretation of the isotherms allowed to approach the Langmuir model with R² of 0.918 and to determine the maximum adsorption capacity (qmáx) as 11.481 mg.g⁻¹. The characterization of biomass by MAS in the Infrared (FT-IR) identified the possible functional groups belonging to protein, fatty acids and lipids, while thermal analysis (TG-DSC) showed a greater removal of inorganic matter by the biomass washed with water. The method underwent analytical validation, being classified as specific, sensitive, linear, robust, precise and accurate, with LD (limit of detection) and LQ (limit of quantification) equal to 3.873 and 12.912 mg.L⁻¹, respectively. The results obtained demonstrated the potential use of mesocarp Baru as a natural adsorbent for copper ions in solution, opening power for future expansion and improvement of the method.
