Precision Analysis of Lanthanides by Fluorescence Spectroscopy Part one : Flourimetric Determination of Rare Earths by Ternary Complexes of TTA, n-Octanol and Triton X-100

The fluorescence intensities of europium and samarium can be greatly enhanced in the presence 2-thenoyltrifluoroacetone(TTA), n-octanol and Triton X-100 in aqueous solution of pH 7. It was also found that the fluorescence intensity can be greatly increased by the addition of excess of . The excitation and emission wavelengths of europium and samarium were 345 nm, 380 nm and 617 nm, 567 nm, respect…
