摘要

The extraction properties of bis[N-alkyl-N-(2-diphenylphos-phorylethyl)]diglycolamides [Ph2P(O)CH2CH2N(R)C(O)CH2]2O (R = Me, Bu, Oct) towards rare-earth element(III) ions are studied in perchlorate media. It is established that the modification of diglycolamides with additional P(O)Ph2 coordinating groups in the amide units of the molecule leads to an increase in the efficiency of extraction of rare-earth element(III) ions from perchloric acid solutions.
