Dr. Mª Fresnedo San Roman and Dr. Eugenio Bringas attended the 21st International Solvent Extraction Conference (ISEC 2017) that took place in Miyazaki (Japan) from November 5th to 9th, 2017. During the conference they presented the works “Recovery of valuable compounds from spent pickling solutions by the combination of liquid membranes and electro-membrane technologies” (oral presentation), “CFD analysis of interfacial mass transfer in micro-solvent extraction processes” (poster presentation) and “Membrane-based solvent extraction for cobalt(II) separation using Cyanex 272” (poster presentation).
