“…The radioisotopes are produced from many applications such as nuclear fuel, medical diagnoses, and treatment (Zhang et al 2019 ; Abdel Maksoud et al 2022 ). One of the fission products generated by irradiated nuclear fuel is lanthanides elements (Vergas et al 2021 ; Lankapati et al 2021 ). Also, lanthanide elements have a distinct application in many fields, for example, metallurgy and the ceramic industry.…”

Graphite (GR) and graphite/alginate (GRA) composite were synthesized utilizing the thermal annealing technique and used as a new adsorbent material for the selective separation and removal of La(III) and Ce(III) from aqueous solutions. Fourier transform infrared (FTIR) spectroscopy, thermal analysis (DTA, TGA), X-ray diffraction (XRD), surface area, porosity, and scanning electron microscope (SEM) were also used to characterize the generated material. Distinct experiments were performed to test the ability of the GRA to La(III) and Ce(III) removal, which include the effect of pH, shaken time, initial concentration of La(III), and Ce(III) at different temperatures range. After 20 min, both ions have reached equilibrium. The pseudo second-order kinetic model was chosen as one which best fits the experimental evidence and better reflects the chemical sorption process. Adsorption isotherm was studied using the Langmuir, Freundlich, and D-R models. The Langmuir model was used to better fit the results obtained. At 25 °C, Ce(III) and La(III) have maximum monolayer capacities of 200 and 83.3 mg/g, respectively. The sorption was endothermic reaction and spontaneous, as illustrated by the data of thermodynamics studies. GRA has the ability to be used as a novel lanthanide adsorbent material, especially for selective separation between Ce(III) and La(III).

The contamination of water by heavy metals poses a significant threat to both the environment and public health, and hence, the effective purification of contaminated water remains a formidable challenge. Recently, graphene oxide (GO) has shown significant potential for removing heavy metals due to its large surface area, availability of functional groups, and high adsorption affinity. However, it is associated with several disadvantages such as aggregation, reduced surface area, and pH sensitivity. To overcome such drawbacks, the surface of GO has been modified with zirconium and amino trimethylene phosphonic acid (ATMP), forming the GO-ZrATMP composite. The newly synthesized hybrid GO-ZrATMP composite has been well characterized by several characterization techniques such as Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), scanning electron microscopy with energydispersive X-ray spectroscopy (SEM-EDS), X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HR-TEM), etc. This composite has been employed for the adsorption of Pb 2+ , Cd 2+ , and Hg 2+ from aqueous solution. Adsorption isotherm and kinetics results showed that the adsorption of Pb 2+ , Cd 2+ , and Hg 2+ on GO-ZrATMP was a monolayer adsorption process and dominated by physisorption and intraparticle diffusion. Thermodynamic studies revealed that the sorption process is endothermic, spontaneous, and feasible. The maximum adsorption capacity was found to be 373, 320, and 281 mg/g for Pb 2+ , Cd 2+ , and Hg 2+ , respectively. Further, a study pertaining to distribution studies (in aqueous and various electrolyte media) and metal separations has been conducted. Based on these studies, efficient binary and ternary metal separations have been achieved using GO-ZrATMP composite material. The present study clearly demonstrates the potential of GO-ZrATMP composite in eliminating heavy metals from both water and real wastewater.

“…Different applications that include medicine, food, hydrometallurgy, and oil sectors have all used ion exchange systems. Many ion exchange resins have been utilized for REE separation (Lankapati et al 2021 ; Ni et al 2021 ). Biosorption has been proposed as an option for the separation of REE because of its cost, efficiency, and simplicity in REE separation from low concentrations effluents.…”

With the growing need for high-purity rare-earth elements (REEs), the separation of these REEs has received much attention recently. The objective of this research is to produce chitosan from shrimp waste, then modify it with different functionality, and investigate the adsorption properties of chitosan adsorbents towards La(III) ions. First, from shrimp waste, chitosan (ch) with a significant degree of deacetylation, purity, and solubility was produced. The purified chitosan was cross-linked with epichlorohydrin (ep), and then, it was modified with 3,6,9,12-tetraazatetradecane-1,14-diamine (HA) to produce polyaminated chitosan (HA@ep@Ch). The polycarboxylated/imine chitosan (CM@HA@ep@Ch) was obtained by treating polyaminated chitosan with chloroacetic acid in isopropyl alcohol. The chitosan adsorbents were characterized and applied for lanthanum recovery from synthetic and monazite leach liquor samples. The factors controlling the recovery process were studied and discussed. The performance of the adsorbents was achieved through equilibrium, dynamic, and isothermal studies. HA@ep@Ch and CM@HA@ep@Ch showed good performance for lanthanum recovery with a maximum capacity of 114.52 and 141.76 mg/g at 330 K, respectively. The isotherm parameters refer to the monolayer of lanthanum adsorbed into the adsorbents through chelation and ion exchange mechanisms. A 0.5-M HCl solution was found effective to elute 95.8% of the adsorbed lanthanum on HA@ep@Ch, and 93.4% of the adsorbed lanthanum on CM@HA@ep@Ch. The adsorbents showed greater selectivity in extracting La, Ce, Pr, Nd, and Sm (62–75%) from REE leach liquid compared to extracting other REEs (20–41%).
