Scandium, a valuable element with restricted production sources mainly situated in China and Russia, is typically obtained as by-product during the of various materials. As demand for scandium grows expanding aluminum fuel cell industries, significant investments rare earth mining USA Australia, there need to explore alternative recovery sources. This research investigates from an acid pregnant...

Metal speciation studies are of great importance in assessing metal bioavailability aquatic environments. Functionalized membranes a simple tool to perform chemical speciation. In this study, we have prepared and tested polymer inclusion membrane (PIM) made the cellulose triacetate (CTA), extractant di-(2-ethylhexyl) phosphoric acid (D2EHPA), plasticizer 2-nitrophenyloctyl ether (NPOE) as senso...

The effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of Ni and Co from a dilute sulfate media. The separation of Co and Ni was improved by introducing acetate to aqueous media. By the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the aceta...

An update is presented on liquid membrane-based processes as viable and relevant alternatives to conventional approaches such as precipitation, solvent extraction, ion exchange processes and electrochemical techniques for the removal and recovery of some toxic and/or valuable trace metal ions including some actinides and fission products e.g. U, Am, Y etc and As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Zn ...
