Summary
The spectrofluorimetric determination of terbium(III) in ethanol (95%) solution of acetylacetone (3×10−4 mol/l) was studied. Intensive fluorescence of terbium(III) (λ=545 nm) was observed after excitation of the system (λ=310 nm). The method proposed is satisfactory for the determination of terbium(III) in the range of 4 to 40 ng/ml (2.5×10−8 to 2.5×10−7 mol/l). The effect of other rare earths, common metal ions and anions upon the intensity of the fluorescence emitted by terbium(III) is discussed.
