Conversion of Lithium Chloride into Lithium Hydroxide by Solvent Extraction KU Leuven

Viet Tu Nguyen, Clio Deferm, Sofía Riaño Torres, Peter Tom Jones, Koen Binnemans

UNLABELLED: A hydrometallurgical process is described for conversion of an aqueous solution of lithium chloride into an aqueous solution of lithium hydroxide via a chloride/hydroxide anion exchange reaction by solvent extraction. The organic phase comprises a quaternary ammonium chloride and a hydrophobic phenol in a diluent. The best results were observed for a mixture of the quaternary ammonium chloride Aliquat 336 and 2,6-di-tert-butylphenol ...

Electrochemical behavior and electrodeposition of gallium in 1,2-dimethoxyethane-based electrolytes KU Leuven

Wouter Monnens, Pin-Cheng Lin, Clio Deferm, Koen Binnemans, Jan Fransaer

The electrochemical behavior and electrodeposition of gallium was studied in a non-aqueous electrolyte comprising of gallium(III) chloride and 1,2-dimethoxyethane (DME). Electrochemical quartz crystal microbalance (EQCM) and rotating ring disk electrode (RRDE) measurements indicate that reduction of gallium(III) is a two-step process: first from gallium(III) to gallium(I), and then from gallium(I) to gallium(0). The morphology and elemental ...
