Electrochemistry Of Rhodium (III) In Trihexil(tetradecyl) Phosphonium Bis(2,4,4-trimethylpentyl) Phosphinate Ionic Liquid (Cyphos IL 104) And Its Deposition

摘要

A fast liquid-liquid extraction of Rh (III) from acidic HCl solutions by Cyphos IL 104 and the Rh (III) stripping has been performed followed by electrodeposition of metal ion directly from ionic liquid phase. The reduction of Rh (III) to metallic Rh occurs at -1.4 V pseudo reference electrode of Pt. A further electrolysis at this constant potencial shows that it was possible to obtail metallic rhodium contained in Cyphos IL 104.
