Extractive complexation of lanthanides and Am(III) by 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone in ionic liquid: Solvent extraction and spectroscopic studies

Extraction behaviour of trivalent actinides and lanthanides was studied using solutions of HPMBP in a room temperature ionic liquid and the nature of the extracted species was investigated by slope analysis, luminescence spectroscopy and thermodynamic studies. Complex formation constants with Nd3 + ions were reported for the first time.
