Electrochemistry of Rhodium (III) in Trihexil(tetradecyl) Phosphonium Bis(2,4,4-trimethylpentyl) Phosphinate Ionic Liquid (Cyphos IL 104 ®) and Its Deposition

Electrochemistry of Rhodium (III) in Trihexil(tetradecyl) Phosphonium Bis(2,4,4-trimethylpentyl) Phosphinate Ionic Liquid (Cyphos IL 104 ®) and Its Deposition

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...

Zusammenfassung: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
