Abstract
The new macrocylic ligand, H3do3a-pyNO, forms thermodynamically stable and kinetically inert Ln(III) complexes. Its Eu(III) and Tb(III) complexes exhibit a strong long-lived fluorescence as a result of the antenna effect of the pyridine-N-oxide fluorophore pendant arm. Using an excitation wavelength of 286 nm, this ligand can be employed as a fluorogenic reagent for the determination of Eu(III) and Tb(III) at pH 6.5 and cL = 1 mM detected lumiscence at 615 nm for Eu(III) complex and at 547 nm for Tb(III)complex. Detection limits are at concentrations around 1.0 mikroM and linearity of the method spans over 2 orders of magnitude. The method was applied to artificial and real samples (spiked mineral waters, extracts from luminophore CRT dust) with satisfactory results. The method is simple and rapid without interfering other metal ions.
