COMPLEX FORMATION OF EUROPIUM WITH THENOYLTRIFLUOROACETONE AND TRI-n-OCTYLPHOSPHINE OXIDE IN MICELLAR SOLUTION OF NONIONIC SURFACTANT
The distribution behavior of europium between micellar and bulk phases was investigated in aqueous solutions of europium-TTA and europium-TTA-TOPO complexes with nona-oxyethylene dodecyl ether by spectrophotofluorimetric method. Apparent equilibrium constants of these complexes were estimated.
