Abstract
In the present work, the kinetics of transport of selected rare earth ions at the liquid-liquid interface in the presence of a magnetic field gradient was investigated. A uniform magnetic field was applied to the classic liquid-liquid solvent extraction system. The influence of temperature, initial concentration of selected ions and magnetic field gradient on the extraction rate was determined. It was shown that the uniform magnetic field could affect the kinetics of the extraction of rare earth ions in the liquid-liquid system. The observed differences constitute a promising prospect worthy of further research. Figs 6, Refs 10.
