“…The lanthanide reactivity to activated carbon from banana peels is La> Ce> Y>Nd> Sm. A similar trend was observed with the adsorption of trivalent La, Ce, and Nd ions using biochar composites, with the maximum removal of lanthanide ions being achieved at an adsorbent dosage of 0.1 g, pH of 4, and contact time of 360 min (Kolodyńska et al, 2018). After the adsorption process, the equilibrium pH reached 4.…”

Lanthanides in aqueous waste streams have received great attention due to their ability to pollute the environment. Therefore, efforts have been devoted to adsorbing lanthanides from waste industries. The evaluation of agro-waste by determining the adsorption efficiency of Ln 3+ ions is an important step in developing a process for Ln 3+ removal from water systems, as well as a method of isolating Ln 3+ ions from mineral ores, such as low-grade bauxite. The adsorption performance of banana peels (Musa paradisiaca L.) was evaluated in the removal of Ln 3+ ions. In addition, the adsorption of lanthanide ions from an aqueous solution in a multicomponent system was studied using activated carbon from banana peels. The selection of the best adsorbent was done by the iodine number method, where activated carbon had the highest iodine absorbance at 572.2 mg/g. The use of activated carbon as an adsorbent for the removal of commercial lanthanide ions from an aqueous solution was evaluated. The optimum condition in the Ln 3+ multicomponent system for the adsorption of Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ ions was determined to be a contact time of 2.5 h, a pH of 4, and an adsorbent dosage of 100 mg. The present research further supports the possibility of the adsorption of Ln 3+ ions from low-grade bauxite with adsorption efficiencies of 67.6, 71.0, 65.0, 62.9, and 56.6% for Y 3+ , La 3+ , Ce 3+ , Nd 3+ , and Sm 3+ , respectively.

“…The apparent rate coefficients (k 1 × 10 2 min −1 ) are of the same order for the three sorbents (though, in the case of MC, a greater dispersion of the data is observed): 3.11 ± 0.73, 3.26 ± 0.05, and 3.81 ± 0.08 min −1 , for MC, MC-UR, and MC-UR/S, respectively. These values are of the same order of magnitude as the apparent rate coefficients reported by Kołodyńska et al [ 31 ] (0.8–1.4 10 −2 min −1 ) for Nd(III), Ce(III), and La(III) using composite biochar.…”

“…Sorption processes are usually preferred to solvent extraction for the treatment of low-concentration effluents. A wide range of materials have been reported for cerium or REE sorption, including biosorbents [ 25 , 26 , 27 , 28 , 29 , 30 ], carbon-based supports [ 24 , 31 , 32 ], inorganic sorbents [ 33 , 34 ], and chelating and ionic-exchange resins [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ].…”

The recovery of strategic metals such as rare earth elements (REEs) requires the development of new sorbents with high sorption capacities and selectivity. The bi-functionality of sorbents showed a remarkable capacity for the enhancement of binding properties. This work compares the sorption properties of magnetic chitosan (MC, prepared by dispersion of hydrothermally precipitated magnetite microparticles (synthesized through Fe(II)/Fe(III) precursors) into chitosan solution and crosslinking with glutaraldehyde) with those of the urea derivative (MC-UR) and its sulfonated derivative (MC-UR/S) for cerium (as an example of REEs). The sorbents were characterized by FTIR, TGA, elemental analysis, SEM-EDX, TEM, VSM, and titration. In a second step, the effect of pH (optimum at pH 5), the uptake kinetics (fitted by the pseudo-first-order rate equation), the sorption isotherms (modeled by the Langmuir equation) are investigated. The successive modifications of magnetic chitosan increases the maximum sorption capacity from 0.28 to 0.845 and 1.25 mmol Ce g−1 (MC, MC-UR, and MC-UR/S, respectively). The bi-functionalization strongly increases the selectivity of the sorbent for Ce(III) through multi-component equimolar solutions (especially at pH 4). The functionalization notably increases the stability at recycling (for at least 5 cycles), using 0.2 M HCl for the complete desorption of cerium from the loaded sorbent. The bi-functionalized sorbent was successfully tested for the recovery of cerium from pre-treated acidic leachates, recovered from low-grade cerium-bearing Egyptian ore.

“…In this respect, the adsorption technique has been documented as an essential mode for elimination of metals such as yttrium and other lanthanides because of its high speed and naturalness and efficiency of operation and because they are relatively cheap and abundant available adsorbents . Numerous biosorbents and sorbents involving zeolites, natural clays, nanomaghemite, calcium alginate, metal oxides, and other materials have been investigated as efficient adsorbents for isolation and separation of yttrium and/or the rest of lanthanides from different matrices. − The biochar composites also were found to establish powerful elimination of lanthanide elements as neodymium(III), lanthanum(III), and cerium(III) ions . A layer-by-layer technique appeared to be effective static removal of yttrium ions …”

Yttrium is a remarkable rare-earth element with multidiscipline applications, and it can be released into an aquatic system for its widespread industrial applications. The present work is devoted to evaluate the kinetics and isotherm models for adsorption of Y(III) ions by the action of a novel metal–organic framework (MOF) chemically bonded polymer with incorporated ion exchange and chelating characters. To assemble these MOFs, a number of synthetic procedures were designed and performed using microwave irradiation heating in only 12 min. (i) The selected MOFs were synthesized by the reaction of zinc acetate and glutaric to produce (ZnGA) in 3 min. (ii) Covalent bonding and coating of (ZnGA) with 3-aminopropyltrimethoxysilane were carried out to produce (ZnGA–Si–NH2) in 3 min. (iii) The polymeric compound was synthesized by coupling of p-chlorocresol with piperazine via formaldehyde to yield PC in 4 min. (iv) The final MOFs–polymer nanocomposite was synthesized by the functionalization of ZnGA–Si–NH2 with PC to assemble ZnGA–Si–NH–PC in 2 min. The impact of the polymer on stability of ZnGA–Si–NH–PC in aqueous solutions (pH 1–7) was confirmed and compared to the MOFs separately. Additionally, thermal stability and surface morphology of ZnGA–Si–NH–PC were also studied and evaluated. The metal sorption capacity values of Y(III) ions onto ZnGA–Si–NH–PC were optimized at pH 7 and established as 1175, 1925, and 4800 μmol g–1 using 0.025, 0.05, and 0.1 mol L–1 of Y(III), respectively. The interaction mechanisms for binding of Y(III) ions with ZnGA–Si–NH–PC were studied and evaluated by seven kinetics models and seven adsorption isotherm models, and the collected results confirmed that the adsorption process is well fitted with the pseudo-second-order and pore diffusion models. The collected data assured that the adsorption of Y(III) ions onto the ZnGA–Si–NH–PC nanocomposite is chemisorption (ΔH° = 42.44 kJ/mol) with the direct ion exchange mechanism of Y(III) ions with the surface hydrogen ions and coordinate bond formation mechanism with the nitrogen functional groups into the available pores of the ZnGA–Si–NH–PC nanocomposite.
