“…In conclusion, to obtain better removals and recoveries of metal is necessary to continue studying the initial concentration, molar ratios of elements from wastewaters, pH of catholyte, applied cell potential, flow regimes, inter alia as it can be proved with the scientific articles mentioned above [ 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ].…”

Although the first published works on electrodeposition dates from more than one century ago (1905), the uses of this technique in the recovery of metals are attracting an increasing interest from the scientific community in the recent years. Moreover, the intense use of metals in electronics and the necessity to assure a second life of these devices in a context of circular economy, have increased the interest of the scientific community on electrodeposition, with almost 3000 works published per year nowadays. In this review, we aim to revise the most relevant and recent publications in the application of electrodeposition for metal recovery. These contributions have been classified into four main groups of approaches: (1) treatment and reuse of wastewater; (2) use of ionic liquids; (3) use of bio-electrochemical processes (microbial fuel cells and microbial electrolysis cells) and (4) integration of electrodeposition with other processes (bioleaching, adsorption, membrane processes, etc.). This would increase the awareness about the importance of the technology and would serve as a starting point for anyone that aims to start working in the field.

“…Ali reported that approximately 339 g of silver can be recovered by BES in an ecofriendly manner from 1.5 L of low concentrated wastewater (500 mg/L) after 30 days, leading to a 67.8% silver recovery ratio, high pure crystalline (99%) products, and 3006 mW/m 3 bioenergy. Kaur developed the 6.8 L BES system for the 50–1000 mg/L copper recovery from distillery effluents, resulting in 60–95% copper deposition. Huang et al reported a complete MFCs recovery of mixed Sn 2+ , Fe 2+ , and Cu 2+ , with simultaneous copresent organic remediation in synthetic wastewater of printed circuit boards (PCBs).…”

Due to the widespread application of heavy metals in steel making, electronics, batteries, leather tanning, and catalysis, considerable toxic heavy metal-bearing wastewater and solid waste are directly or indirectly discharged into surrounding environments. Recently, electrochemical methods have attracted considerable attention for the remediation of metal pollution, originating from their environmental compatibility, high efficiency/selectivity/feasibility, and cost effectiveness. This review aims at recent advances in electrochemical metal recovery techniques, such as electrodeposition, electrosorption, electrodialysis, electrodeionization, and bioelectrochemical and photoelectrochemical methods. Additionally, the mechanisms and behaviors of different strategies are reviewed and compared, to overcome the limitations of concentration polarization from dilute metal ions, production of dendrites and spongy deposits, sluggish kinetics of ions transportation, and side-reactions from the hydrogen evolution and oxygen reduction reactions. Furthermore, the current challenges and future prospects of electrochemical metal recovery applications are also provided, to establish a process–mechanism–products (PMP) rational design of metal recovery, rather than simple metal removal.

“…Kaur et al 17 studied the copper recovery in a bioelectrochemical system using synthetized and real distillery effluents (relatively high copper concentration, i.e., 1 g/L followed by a lower concentration, i.e., 50 mg/L). 60-95 % copper was recovered in the form of deposits depending on starting concentration.…”

This study permits to explore the interactions involved in Lewis acid (AlH3) and Lewis bases: CO; H2O; NH3; PH3; PC13; H2S; CN–; OH–; O2–2; F–; N(CH3)3; N2; N2H4; N2H2; C5H5N; C6H5-NH2. By means of DFT theory calculations with B3LYP functional using 6-31G(d,p) basis set and in order to check the effects of both the donor and the acceptor in the establishment of the different adducts we focused mainly on the calculation of the energetic gap ∆EHOMO-LUMO, Gibbs energies ∆G, the angle (θ) in AlH3-base and the interaction energy values Einter. The several parameters of the reactivity (electrophilicity index (ω), nucleophilicity (N), chemical potential (μ), hardness (η), and polarizability (α)) are also calculated to define the weak interaction as well as to distinguish between the nucleophilicity and basicity of different Lewis bases. The results showed that the electronic charge transfer is estimated to be important in the systems where the interaction is established between Al and anionic bases, and the electron donor power is predictable for O–2, F–, OH–, and CN–. The pseudo-tetrahedral adduct arrangements depend on the parameter geometries (bond length interaction and θ angle) and Gibbs energies ∆G characterizing the main stability.
