Changes in the morphological properties and functional components of PMA biosorbent were characterized using SEM-EDX, FT-IR, BET, and PZC analyses. The effect of various parameters such as initial Pb2+ concentration, pH, PMA dosage, contact time, and temperature on biosorption was investigated using a batch biosorption procedure. The maximum biosorption capacity, determined using the Langmuir isotherm, was calculated to be 119 mg g(-1). It was found that the biosorption kinetic mechanism followed pseudo-second-order kinetics and intraparticle diffusion model. According to the determined thermodynamic parameters, the biosorption mechanism was found to be endothermic (Delta H degrees > 0), spontaneous (Delta S degrees > 0), and entropy-increasing (Delta G degrees < 0). The outcomes of the experiment were evaluated in comparison to other sorbents that have been previously commonly used in the literature. It was demonstrated that PMA could be a promising, environmentally friendly, cost-effective, and sustainable potential biosorbent for the removal of Pb2+ ions.en10.1007/s13399-024-05775-zinfo:eu-repo/semantics/openAccessBiowasteBiosorptionLeadWastewater treatmentArticle2-s2.0-85195196948Q3WOS:001255277200005N/A
