The coordination chemistry of trivalent lanthanides with chelidamic acid was studied using fluorescence and absorption spectroscopic methods. The speciation was determined using Eu(II1) fluorescence techniques. The stability constants and the oscillator strengths were determined for the Ho(II1) complexes from absorbance measurements of a Ho(II1) hypersensitive transition. The lanthanide coordination chemistry of chelidamic acid and dipicolinic acid is compared.

A study of the variation of the distribution coefficients of thenoyltrifluorotone (HTTA) and Sm with time has been made in the synergistic system kerosine/HTTA/tributylphosphate (TBP)/dilute HNOI. The results indicate that the phenomena of antagonism or antisynergism which takes place at TBP concentrations above 0.1 M is due to the large reduction of the free HTTA-enol in the organic phase and to a much lesser extent to the reduction of the free TBP concentration in the same phase through the formation of HTTA-HZO and HTTA-HzO-TBP, respectively. Equations which allow calculation of the free HTTA-enol and free TBP are developed.
