Turanov, A. N. published the artcileExtraction of Rare-Earth Elements(III) with Mixtures of 1-Phenyl-3-methyl-4-benzoyl-5-pyrazolone and Phosphoryl-Containing Podands, Formula: C17H14N2O2, the publication is Russian Journal of General Chemistry (2019), 89(9), 1830-1835, database is CAplus.
Extraction of rare-earth elements(III) ions from chloride solutions with mixtures of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone and phosphoryl-containing podands in organic solvents has been studied. The observed significant synergistic effect is associated with the formation of hydrophobic mixed-ligand complexes of rare-earth elements(III). The stoichiometry of the extracted complexes has been determined, and the extraction constants have been calculated The influence of the phosphoryl-containing podand structure, the organic solvent nature, and the aqueous phase composition on the efficiency of the extraction of rare-earth element(III) ions into the organic phase has been considered.
