Karazin popup.description2 The object of the study is the interaction of metal-toxicants with sensor compounds, an analytical signal of which is able to provide sensitive qualitative and quantitative determination of some target ions in the presence of ions of other types, as well as multi-parameter determination in multicomponent mixtures. The subjects of the research are: organic fluorescent dyes and their complexes with heavy metal ions ,which are toxicants and pollutants of the environment, as well as polymeric sensor matrices containing metal-sensitive organic compounds; changes in spectral properties of sensor matrix components - fluorescent dyes and sensory matrices in general by the action of individual metals-toxicants or multicomponent mixtures of these ions; optimal methods for processing multi-parameter analytical signals from developed sensor matrices. The purpose of the work is to create model polymer matrices containing various fluorescent dyes, which enable simultaneous determination of concentrations of some toxic metal ions - environmental pollutants - mercury, cadmium, lead, and others. The general fundamental problem is the simultaneous analysis of one or even several metal ions contained in environmental objects. It is an important problem that until now has only partially solved. Express methods of simultaneous separation analysis of several macro- and trace elements, heavy toxic metals in their multicomponent mixtures are currently absent. The fundamental task in the framework of general problem are synthesis, investigations of physical and chemical properties of fluorescent dyes ha ving complex formation sites and providing the formation of a multiparametric spectral analytical signal, when interacting with heavy metal ions in the polymer matrix.
