Frequency and atomic mass based selective electrochemical recovery of rare earth metals and isotopes

摘要: Abstract Rare earth metals (REMs or lanthanides) are highly useful in applications such as gas sensors, hybrid vehicles, defense equipment, fluorescent and LED lights, metal alloys, well the production of electrical assemblies associated magnets. The energy 4f electrons lanthanides is relatively less than that outer valence electrons. In other words these localized part ionic core. addition, do not directly participate compound forming processes. This a main cause for difficulty chemically separating similar lanthanides. One possible separation technique utilizes effect atomic mass based dispersion, involves application potential with different oscillating frequencies. At lower frequency, range distribution REMs deposited greater at higher frequency. this paper, we present step-by step approach formulation to electrochemically separate REMs.
