Karazin popup.description2 The main aim of this investigation is the design of fluorescent dyes containing polymeric matrices, which make possible simultaneous detection of several toxic heavy metals ions - Mercury, Cadmium, Lead, etc. in the environmental samples. The object of investigation - interaction of toxic heavy metal ions with chemosensing compounds with formation of analytic signal assuring sensitive qualitative and quantitative detection of definite ions and/or multiparametric detection in their complex mixtures. The subject of investigation - organic fluorescent dyes and their complexes with toxic heavy metals ions, environmental contaminants. Polymeric sensor matrices containing metal-sensitive organic complexing compounds. Changes of the spectral parameters of the components of chemosensing matrices- fluorescent dyes or the matrices as a whole under the influence of definite toxic ions or their multicomponent mixtures. Optimal methods of mathematical treatment of the analytical signals from the developed sensing matrices. The general fundamental problem, on resolving of which this work is directed - simultaneous analysis of the definite toxic ions orseveral toxic ions at the same time in the environmental samples. Their solution was achieved only partially. Express methods of simultaneous discriminative analysis of several macro- and micro-elements, toxic heavy metals in their multicomponent mixtures are still absent up to now.The specific fundamental task within the general problem, which was tried to resolve on the first stage of this work - synthesis and selection of fluorescent dyes with complexing centers, which allow obtaining of complex and multidirectional analytical signal at interaction of the above mentioned metals.
