摘要：

Mechanisms for the extraction of rare earth metals with a binary extracting agent based on bis(2,4,4-trimethylpentyl)phosphinic acid with the formation of various complexes in the organic phase were proposed. The compositions of the extracted compounds were determined, and the distribution of these compounds was adequately described by calculated curves.
