  "abstract": "Lignocellulosic felts derived from hemp and flax were investigated as sustainable biosorbents for manganese ions removal from aqueous solutions, both in their native form and after functionalization through 1,2,3,4-butanetetracarboxylic acid (BTCA) grafting. Batch experiments were conducted to assess the influence of initial metal concentration, adsorbent dosage, pH, and ionic strength on biosorption performance. BTCA modification significantly enhanced Mn2+ uptake, with flax-based felts outperforming hemp due to their higher α-cellulose content, finer fiber morphology, and larger effective surface area. Mn2+ removal increased with adsorbent dosage and reached its maximum at pH values promoting deprotonation of BTCA carboxyl groups, confirming a complexation-driven mechanism. Increasing the solution ionic strength (0.1-0.5 M NaCl) reduced removal efficiency by competitive Na+ interactions with cellulose, hemicellulose, and BTCA-derived -COO− groups, though modified felts maintained superior performance. Adsorption isotherm modelling revealed distinct behaviors among materials: native felts fit moderately well to the Langmuir model, while BTCA-modified flax showed excellent agreement with Langmuir and Dubinin–Radushkevich models. The mean free energy of 18 kJ mol−1 confirmed chemisorption via metal-carboxylate coordination as the dominant mechanism. Overall, BTCA-modified flax felts emerged as highly effective and environmentally friendly biosorbents, offering strong potential for Mn2+ removal in industrial wastewater treatment applications.",
