Extraction of Au(III), Pt(IV), and Pd(II) from Aqueous Media with Deep Eutectic Solvent Dissolved in n-Heptane as Extractant

Autor: Pius Dore Ola, Michiaki Matsumoto

Publikováno v: Indonesian Journal of Chemistry, Vol 23, Iss 6, Pp 1735-1741 (2023)

Due to the scarcity, studying precious metals extraction such as gold, platinum, and palladium is very critical. Solvent extraction is one of the established methods due to its simplicity and quickness but the low operational cost. In this study, a d

Extraction Mechanism of Ferric and Manganese Ions with Aqueous Two-phase System Formed by Ionic Liquid and Polyethylene Glycol

Autor: Michiaki Matsumoto, Pius Dore Ola

Publikováno v: Chemical and Biochemical Engineering Quarterly
Volume 33
Issue 2
Chemical and Biochemical Engineering Quarterly, Vol 33, Iss 2, Pp 229-234 (2019)

In this work, we employed an aqueous two-phase system formed by an ionic liquid and polyethylene glycol for the separation of Fe(III), which is the most commonly used metal in the world, and Mn(II), which is currently used in many industries. We foun

Determination of Fe(III) in manganese processing’s waste water using digital image methods with Terminalia catappa L. leaves extract as a complexing agent

Autor: Luther Kadang, Sherlly M. F. Ledoh, Suwari, Novia R. Tuda, Philiphi de Rozari, Pius Dore Ola

Publikováno v: 3RD INTERNATIONAL CONFERENCE ON CHEMISTRY, CHEMICAL PROCESS AND ENGINEERING (IC3PE).

Generally, chemical analysis-including metal ions analysis-involves the use of complexing agents that react with analytes to produce color change which can be used to identify the analytes both qualitatively and quantitatively. The disadvantages of u

Use of deep eutectic solvent as extractant for separation of Fe (III) and Mn (II) from aqueous solution

Autor: Michiaki Matsumoto, Pius Dore Ola

Publikováno v: Separation Science and Technology. 54:759-765

In this work, we used deep eutectic solvent (DES) composed of decanoic acid and lidocaine, which is characterized as a green solvent, for separation of Fe (III), which is the most-used metal in the...
