Primary Dataset of structural, morphological, magnetic, and adsorption data of a hexaferrite-based magnetic composite for lead removal

Primary open-access research database deposited in Zenodo containing raw and processed data derived from the synthesis and evaluation of a hexaferrite-based magnetic composite for Pb(II) adsorption from aqueous solution. The repository includes original X-ray diffraction (XRD) files, SEM micrographs, magnetic characterization data, and Excel spreadsheets containing experimental adsorption results, removal efficiencies, adsorption capacities, and adsorption isotherm modeling. The dataset was organized to ensure reproducibility, traceability, and scientific reuse, including experimental conditions, operational parameters, and mathematical fitting of adsorption models.
