Electrodeposition of Copper Metal from the 1-Ethyl-3-methylimidazolium Fluoride ([EMIM]F)-urea-H₂O System Containing Cu₂O

Abstract

In this work, [EMIM]F-urea-H 2 O system is capable of dissolving Cu 2 O, and then the metallic copper was electrodeposited from this system at room temperature. The reduction of Cu (I) in this system involves a quasi-reversible and one-step single-electron transfer process. The electrodeposition of copper was performed on a tungsten (W) substrate at −0.67 V (vs. Ag) and 353 K via potentiostatic electrolysis. The electrodeposits were identified as metallic copper, as verified by XRD and EDS. SEM image shows that uniform, polygonal nanoparticles of copper were obtained after the potentiostatic static electrolysis.

Combining phytoremediation and biorefinery: Metal extraction from lead contaminated Miscanthus during pretreatment using the ionoSolv process

“…The competition for ligands to form metal-IL complexes would be a limiting factor at such high concentrations of metals. 64,67,68 Further recycling studies to understand the impact of electrodeposition time, its kinetics, a wider range of electric potentials used to remove all metals present should be investigated. The complexity of such system comes from the presence of a wide range of contaminants, as well as pretreatment degradation products and water.…”

Metal mobility and toxicity of reclaimed copper smelting fly ash and smelting slag

“…24 The copper and zinc in RCS y ash and smelting slag can be leached using water or dilute sulfuric acid, and the leaching solution and leach residue can be treated using other methods. [25][26][27] However, limited information was found regarding the metal mobility and toxicity of RCS y ash and smelting slag.…”
