Electrochemical behavior and electrolysis of Ru( iii ) in molten salts
Abstract
. Constant-potential electrolysis was conducted at -2.5 V to obtain the electrolytic product, which was characterized by X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS). The deposited product was primarily composed of metallic ruthenium. According to inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis, the extraction efficiency of Ru(iii) ions on the nickel electrode reached 88.92%. The current efficiency was 58.93% for constant-potential electrolysis for 2 h. This study demonstrates that the separation of Ru by electrochemical methods in molten salts is feasible.
