摘要：

Experimental and computational studies of metal extraction and separation are performed using lanthanides chlorides in cascade of mixer-settlers connected in the conventional variant and according to the scheme based on the combined techniques of liquid membranes. An increase in the extraction degree of lanthanides, as well as the separation of these metals is found when the combined liquid membrane procedurebased scheme is used with increasing number extractor cascade. The calculated data show that increasing the organic phase flow with respect to the phase flow rate of the raffinate and reextract significantly increase the rate of extraction and separation of lanthanides in the case of circuits based on the combined liquid membrane technology.
