INTENSIFICATION OF EXTRACTION OF RARE EARTH ELEMENTS AT VIBRATION IN A DYNAMIC INTERFACIAL LAYER

The kinetics of extraction of lanthanide chlorides [Ho (III), Pr(III), Nd (III), Yb (III)] in static and flow systems with di-(2-ethylhexyl)phosphoric acid in an inert diluent (heptane, toluene, carbon tetrachloride) was studied in the absence and presence of local vibration in the interfacial layer. The influence of the nature of rare earth elements, the solvent and the initial concentration of the extragent on the coefficient of acceleration extraction is shown
