Abstract: Four new dipicolylamine compounds carrying
anthracene, naphthalene, pyrene and phenanthrene groups were synthesized, and
their ion sensor properties were studied by means of emission spectrometry in
ethanol-water (1:1). It was disclosed that among a series of studied anions and
cations, only with Cd2+, Zn2+, Cu2+ and Hg2+
cations, ligands formed complexes selectively. With spectrofluorimetric
measurements, the complexation stoichiometry and the complex stability
constants of the formed complexes were determined. A linear range from 0.10 µg
L-1 to0.15 mg L-1 where the fluorescence
intensity of the phenanthrene
derivative compound showed a regular decrease with the increase of the Hg2+
ion concentration was obtained. The method developed for the
determination of Hg2+ was applied to tap water samples. In order to
eliminate the matrix effect, a modified standard addition method was used. Detection
and quantification limits were 0.009 mg L-1 and 0.027 mg L-1, respectively.
