Because of their specific properties, the lanthanide elements are increasingly used in diverse applications such as medicine, cosmetics, glass additives, high-intensity lighting, lasers, refractive index lenses, catalysts, the mining industry and nuclear technology [2, 3]. Despite the importance of such elements, the bioaccumulation of REE’sREEs in the food chain, even at trace concentrations, can lead to serious diseases in humans [4]. During the processing of the nuclear fuel cycle, radioactive heavy metals that include actinide and lanthanide elements are produced as a result of multiple neutron capture reactions and nuclear fission. Trivalent ions, especially Ce3+, Nd3+ and Gd3+, can interfere with the calcium channels in both animal and human cells. They can also alter or even inhibit the functioning of various enzymes and, when they exist in neurons, they can regulate synaptic transmission and thus block certain receptors, which lead to significant problems [4]. Accordingly, the segregation, sorption and recovery of lanthanide from metal-containing industrial and nuclear waste streams are of both economic and environmental significance [5]. Moreover, the detention of lanthanides prior to geological disposal is necessary if the long-term efficacy of radioactive waste management is to be ensured. Numerous techniques, for instance co-precipitation, chemical absorption, solvent extraction, biosorption, membrane separation and distillation have been employed for pre-concentration and recovery of REEs [6-9]. Nevertheless, most of these techniques are burdened by numerous limitations, for
Sorption; sorption onto solid surfaces can be assumed to be one of the most satisfactory techniques available today, as the sorption system consists of a simple operationsoperation, is mostly non-toxic, and the straightforward sorbents development [11, 12].

Numerous investigators have synthesized composite sorbents.
