Description

The stability constants of Europium (III) complexes with carbonate and bicarbonate ions are measured at 220C and at 0.5M ionic strength. Solvent extraction with 1.3-diphenyl 1.3-propanedione 5x10-2M in benzene is studied. The distribution between the organic and aqueous phases is determined by radioactive tracers. The limits of the spectrophotometric method and of the solubility in the evaluation of this type of complex are evidenced, mainly in the concentration range useful in geochemistry. Some results obtained with Nd and Am 241 are also given
