Synthesized MgFe2O4 Nanoparticles to Remove Pb2+ from Aqueous Solution

In the present paper, nanosized magnesium ferrite (MgFe2O4) material is synthesized by the hydrothermal method. The size and microstructure of magnesium ferrite 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 is investigated. The adsorption characteristic and Pb2+ removal efficiency of the adsorbent have been determined by investigating the influence of operating variables such as dosage of manganese ferrite. The maximum Pb2+ sorption capacity was found to be 16,08 (mg/g) and obtained using 0,1 g/L MgFe2O4 when pH equals 5, a 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.
