The issue of water pollution has become a major concern in recent times, and the need for effective strategies for treating contaminated water sources has become more urgent. One promising approach that has been gaining attention in the field of wastewater treatment is the use of nano-ferrites. In this regard, novel Mg 0.33 Ni 0.33 Co 0.33 La x Fe 2-x O 4 and Mg 0.33 Ni 0.33 Co 0.33 Gd x Fe 2-x O 4 nanoparticles (NPs), where x= 0.00, 0.01 and 0.08, were synthesized to test their adsorption performance for the removal of Pb (II). The structural properties and morphology were investigated using X-ray diffraction (XRD) and transmission electron microscopy (TEM). As Gd and La content increase, the bandgap energy increases while Urbach energy decreases. The experimental condition for the adsorption process was the adsorbent dosage of 40 mg and contact time of 30, 60, and 90 min at room temperature. Under the recommended conditions, Pb (II) removal% were obtained as 38%, 41% and 75% for Mg 0.33 Ni 0.33 Co 0.33 Fe 2 O 4, Mg 0.33 Ni 0.33 Co 0.33 La x Fe 2-x O 4 with x= 0.01 and Mg 0.33 Ni 0.33 Co 0.33 Gd x Fe 2-x O 4 with x= 0.08, respectively. Therefore, doping ferrite nanoparticles with rare earth metals improve their properties and enable its usage in wastewater treatment particularly for the removal of heavy metals.
