The synthesis of Li1.1Co0.3Fe2.1O4 ferrite nanoparticles has been synthesized by the citrate auto combustion method. The distribution of cations on A-site and B-site was studied by X-ray Diffraction (XRD), High- Resolution Transmission Electron Microscopy (HRTEM). The crystallite size and strain were calculated by using the W–H (Williamson-Hall) plot. The crystallite of Li1.1Co0.3Fe2.1O4 ferrite nanoparticle is ∼30 nm. HRTEM confirmed the homogeneous formation of the cubic phase. The calculated height and spacing parameters related to roughness are essential to achieve the efficiency of Li1.1Co0.3Fe2.1O4 to be used in micro-batteries, smart windows, smart mirrors, displays, gas sensors, and other applications. According to the obtained data, the Li1.1Co0.3Fe2.1O4 has a spiky surface with Rku = 5.50. Additionally, the magnetic hysteresis loop has been clarified using the Vibrating Sample Magnetometer (VSM). The double peak characteristic in the Switching field distribution (SFD) reveals the competition between exchange coupling and strong dipolar interactions. Li1.1Co0.3Fe2.1O4 has employed as a sorbent material for the removal of lead (II) ions from wastewater. The main advantages of the synthesized sample are ease of separation, high adsorption, low cost as well as recycled with notable efficiency. Two models of adsorption isotherms (Freundlich and Langmuir) are utilized to recognize the adsorption mechanism.
