Interactions Between Ionic Liquid (ALiCY) and TBP and their Use in Hydrometallurgy for Extracting Co(II) and Ni(II)
Thanh Tuan Tran, Man Seung Lee
Korean J. Met. Mater. 2020;58(6):423-432.   Published online 2020 May 14
DOI: https://doi.org/10.3365/KJMM.2020.58.6.423

Abstract
Ionic liquids have emerged in hydrometallurgy as potential extractants for metals. In this work, the interactions of ALiCY (R4N+A-) synthesized by Aliquat336 and Cyanex272, and a mixture of ALiCY and TBP, were analyzed using extraction data and FT-IR spectroscopy. Co(II) and Ni(II) were extracted from two HCl concentrations (1.0×10-4 and..... More

Comparison of the Extraction and Stripping Behavior of Iron (III) from Weak Acidic Solution Between Ionic Liquids and Commercial Extractants
Thanh Tuan Tran, Mudassir Iqbal, Man Seung Lee
Korean J. Met. Mater. 2019;57(12):787-794.   Published online 2019 Nov 22
DOI: https://doi.org/10.3365/KJMM.2019.57.12.787

Abstract
Fe(III) can be easily extracted from weak acidic solutions by organophosphorus extractants, but stripping a large amount of Fe(III) from the loaded extractants is very difficult. The extraction and stripping of Fe(III) from 2 pH chloride and sulfate solutions was performed with ionic liquids(ILs) and organophosphorus acidic extractants, and the..... More

Extraction Behavior of Hydrogen Ion by an Ionic Liquid Mixture of Aliquat 336 and Cyanex 272 in Chloride Solution
Minh Nhan Le, Seong Ho Son, Man Seung Lee
Korean J. Met. Mater. 2019;57(3):162-169.   Published online 2019 Feb 8
DOI: https://doi.org/10.3365/KJMM.2019.57.3.162

Abstract
During the extraction of metal ions from a weak acidic chloride solution by ionic liquids consisting of an organophosphorus extractant and Aliquat 336, the equilibrium pH is sometimes observed to be higher than the initial pH. To compare the hydrogen ion extraction behavior of tertiary and quaternary amines, Alamine 336,..... More

Solvent Extraction of Tb(III) from Hydrochloric Acid Solution with Cyanex 272, Its Mixture and Ionic Liquid
염산용액에서 Cyanex 272 및 혼합용매와 이온성 액체에 의한 Tb(III)의 용매추출
Chang Geun Oh, Man Seung Lee
오창근, 이만승
Korean J. Met. Mater. 2018;56(12):870-877.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.870

Abstract
Cyanex 272 shows the highest separation factor for the rare earth elements from hydrochloric acid solution among the organophosporus acidic extractants, D2EHPA and PC 88A. Solvent extraction of Tb(III) from weak hydrochloric acid solution with an initial pH 3 to 6 was compared with Cyanex 272, its mixture with Alamine..... More

Characteristics of Electroless Sn Plating Electrolyte using a Choline Chloride-Based Ionic Liquid
Chieon Park, Bongyoung Yoo, Joonkyun Lee
Korean J. Met. Mater. 2018;56(9):645-651.   Published online 2018 Sep 5
DOI: https://doi.org/10.3365/KJMM.2018.56.9.645

Abstract
In the present study, a choline chloride(ChCl)-based ionic liquid(IL) was used as an electrolyte to confirm the characteristics of electroless tin plating. The effect of the type of additive and reducing agent, as well as the addition of complexing agent and water, on the properties of the ChCl-based IL, including..... More
