Abstract:	This study explores the synthesis of activated carbon (AC) from Posidonia oceanica and composite biopolymer spheres with alginate (AC-PA) for Sr(II) removal. AC and AC-PA were characterized by SEM, XPS, BET, FT-IR, and Zeta analysis. Adsorption isotherms, kinetics, and thermodynamics revealed efficient adsorption. Langmuir isotherm indicated maximum capacities of 55.77 mg/g for AC and 99.95 mg/g for AC-PA. Intraparticle diffusion governed AC adsorption, while AC-PA showed chemisorption and diffusion. Thermodynamics confirmed the endothermic process. Results demonstrate AC and AC-PA as sustainable biosorbents for Sr(II) removal.
