“…Therefore, a set of batch experiments was carried out at a contact time of 2.5:180 min by stirring 0.05 g of DS bioadsorbent with 20 mL of 100 mg.L -1 Th(IV) ions at pH 4 and room temperature. Here, the adsorption kinetic models, such as pseudo-first-and pseudo-second-order models, were applied according to the following equations (Cheira et al, 2019;Gomaa et al, 2018).…”

Removal of thorium ions from acidic media using high effective bio-adsorbent is a very convenient viewpoint for the management of environmental pollutants. With this respect, this study is aimed to synthesize bio-adsorbent derived from date palm seed (DS bio-adsorbent) for adsorption of Th(IV) from acidic media. The studied bio-adsorbent was characterized by FTIR, SEM, and XRD techniques. The effective experimental parameters on the adsorption performance such as pH, bio-adsorbent dose, contact time, solution temperature, thorium initial concentration, and interfering ions were investigated. Furthermore, adsorption isotherm and kinetic studies were explored to describe the mechanism of thorium adsorption using the proposed bio-adsorbent. The Langmuir model result showed that the DS removal adsorption capacity was 43 mg.g-1 at optimized batch conditions. The kinetic findings indicated that the adsorption mechanism was in an agreement with the pseudo-second-order model. Additionally, the regeneration of the spent bio-adsorbent was studied using 0.3 mol.L-1 HNO3 as an eluent agent. This research suggested that the date palm seed bio-adsorbent could be evaluated as a beneficial adsorbent for the adsorption of thorium from aquatic and acidic media due to its selectivity and capacity.

“…This angle is significantly smaller than reported di-oxo-(μ-oxo)-Mo(VI) dimers of monodentate ligands (L mon ), (151–171°). 61 The difference in Mo–O–Mo angles between [Mo 2 O 4 (μ 2 -O)Cl 2 (L mono ) 4 ] and [Mo 2 O 4 (μ 2 -O)(CH 3 OH) 2 (L)] is notable and may be due to higher degrees of freedom of the angles around Mo(VI) centers for the former.…”

An azine-based molybdenum (Mo(VI)) complex (M1) is exploited for selective detection of thorium (Th(IV)) ions through a metal-ion displacement protocol. Th(IV) displaces Mo(VI) from M1 instantly leading to the formation of the Th(IV) complex, having orange-red emission. Consequently, a red shift of the emission wavelength along with 41-fold fluorescence enhancement is observed. This unique method allows detection of Th(IV) as low as 1.5 × 10 –9 M. The displacement of Mo(VI) from M1 by Th(IV) is established by spectroscopic studies and kinetically followed by the stopped-flow technique. The displacement binding constant for Th(IV) is notably strong, 4.59 × 10 6 M –1 . Extraction of Th(IV) from aqueous solution to the ethyl acetate medium using M1 has been achieved. The silica-immobilized M1 efficiently enriches Th(IV) from its reservoir through solid-phase extraction. Computational studies (density functional theory) support experimental findings.

“…State-of-the-art recycling processes (e.g., LithoRec process, a laboratory-scale process by Aalto University) rely on solvent extraction, precipitation, or a combination of these as a way of separation of cobalt and nickel 11 . Also, there have been extensive studies at a laboratory scale for the separation of cobalt and nickel, such as solvent extraction 12 , 13 , precipitation 14 , adsorption 15 – 21 , intercalation 22 , and dialysis 23 , all of which can be beneficial for cobalt/nickel recovery in the NMC chemistry regime. A comparison of different state-of-the-art cobalt/nickel separation techniques is summarized in Supplementary Table 1 to provide benchmarks for selectivity.…”

Selective cobalt and nickel electrodeposition for lithium-ion battery recycling through integrated electrolyte and interface control

et al. 2021

Molecularly-selective metal separations are key to sustainable recycling of Li-ion battery electrodes. However, metals with close reduction potentials present a fundamental challenge for selective electrodeposition, especially for critical elements such as cobalt and nickel. Here, we demonstrate the synergistic combination of electrolyte control and interfacial design to achieve molecular selectivity for cobalt and nickel during potential-dependent electrodeposition. Concentrated chloride allows for the speciation control via distinct formation of anionic cobalt chloride complex (CoCl42-), while maintaining nickel in the cationic form ([Ni(H2O)5Cl]+). Furthermore, functionalizing electrodes with a positively charged polyelectrolyte (i.e., poly(diallyldimethylammonium) chloride) changes the mobility of CoCl42- by electrostatic stabilization, which tunes cobalt selectivity depending on the polyelectrolyte loading. This strategy is applied for the multicomponent metal recovery from commercially-sourced lithium nickel manganese cobalt oxide electrodes. We report a final purity of 96.4 ± 3.1% and 94.1 ± 2.3% for cobalt and nickel, respectively. Based on a technoeconomic analysis, we identify the limiting costs arising from the background electrolyte, and provide a promising outlook of selective electrodeposition as an efficient separation approach for battery recycling.
