Abstract In this study, magnetic biochar-iron oxide (MBC-IO) nanocomposite was easily synthesized as a strong adsorbent to remove toxic Pb(II) heavy metals from aqueous solutions. The physical and chemical properties of the prepared were analyzed using SEM, FTIR, XRD, BET, zeta-potential analyses. An experimental design, response surface methodology (RSM), implemented study effect operational parameters on adsorption performance. maximum capacity MBC-IO found be 504 mg/g, at an dosage 0.08 g/L, pH 7, contact time 10 min, initial lead concentration 50 mg/L. kinetics isotherm studies illustrated that data well described by pseudo-second-order Langmuir models, respectively. addition rapid Pb2+ removal, also employed compare capability Cd2+, Co2+, Ni2+ cations had significant efficiency in removal metals. reusability investigation depicted exhibits properties, enabling its facile separation solutions with assistance external field. These capabilities make good candidate for water purification industries.
