This study synthesizes a magnetic biochar nanocomposite from camel manure via pyrolysis and co-precipitation to remove lead and cadmium from aqueous solutions. The researchers characterize the material using FTIR, XRD, SEM-EDX, and XPS, confirming the presence of iron oxide and surface functional groups. Batch adsorption experiments indicate that the composite achieves high removal efficiencies (97.46% for Pb and 99.17% for Cd) following pseudo-second-order kinetics.
