Korean J. Met. Mater. 2023;61(11):830-841.   Published online 2023 Oct 29
DOI: https://doi.org/10.3365/KJMM.2023.61.11.830

Abstract
This study examined the effects of sulfuric acid concentrations on the corrosion behaviors of three types of commercial steels, conventional carbon steel (SA192), sulfuric acid dew resistant steel (S-TEN), and duplex stainless steel (S32205), considered to be potential materials for the heat recovery steam generator (HRSG) in combined cycle power.....

Korean J. Met. Mater. 2022;60(2):132-140.   Published online 2022 Jan 12
DOI: https://doi.org/10.3365/KJMM.2022.60.2.132

Abstract
Spent electroplating solutions contain a small amount of Pd(II). This Pd(II) can be concentrated by cementation with zinc metal powder. In order to recover pure palladium, a hydrometallurgical process consisting of leaching followed by solvent extraction was developed in this work. First, suitable extractants for the selective extraction of Pd(II)..... More

Korean J. Met. Mater. 2019;57(9):596-602.   Published online 2019 Aug 21
DOI: https://doi.org/10.3365/KJMM.2019.57.9.596

Abstract
Spent lithium ion batteries contain cobalt, copper, lithium, manganese and nickel. Recovery of these metals with high purity from spent lithium ion batteries is of importance. A sulfuric acid solution is generally employed for the treatment of spent lithium ion batteries, but it is difficult to separate these metal ions..... More
