Meshkova, A. Kiriyak, Z. Topilova, V. Antonovich] With the aim of a search for new analytical forms for the determination of praseodymium(III), its 4f luminescence was studied in solutions of mixed-ligand complexes with fluorinated β-diketones and donoractive ligands (1,10-phenanthroline, neocuproine, diantipyrylmethane, diantipyrylpropylmethane, and trioctylphosphine oxide). It was found that the luminescence intensity of praseodymium(III) depends on both the character of the fluoroalkyl substituent in the β-diketone molecule and the nature of the second ligand. The complex of praseodymium(III) with thenoyltrifluoroacetone and diantipyrylpropylmethane was used for the determination of praseodymium in some optical materials. The lower determination limit of praseodymium was 0.01 μg/mL. Pleiades Publishing, Ltd., 2007 Meshkova S.
