In the present paper, nanosized manganese ferrite material was synthesized by the hydrothermal method. The size and microstructure of MnFe2O4 were analyzed based on X-ray diffraction (XRD), scanning electron microscopy (SEM). The nitrogen adsorption-desorption was used for determination of surface area (Brunauer – Emmett – Teller (BET)) and porosity of the fabricated material. The adsorption behavior of Pb2+ using a new magnetic adsorbent was investigated. The adsorption characteristic and Pb2+ removal efficiency of the adsorbent were determined by investigating the influence of operating variables such as dosage of manganese ferrite. The maximum Pb2+sorption capacity was found to be 7.32 (mg/g) and obtained using 0.5 g/L MnFe2O4 at pH 5, temperature of 25 °C, and contact time as 24 h. The Langmuir and Freundlich models were used to fit the experimental data and these showed good correlations.
