Savchuk T. Ion associates of triiodide, iodinebromide and pentachlorophenolate ions with basic dyes and their analytical applications

The thesis is devoted to a comprehensive study of the conditions of formation and properties of the ionic associates of triiodide-, iodinebromide- and pentachloro¬phenolate-ions and basic dyes. The composition and properties of the ionic associates, the dependences between thermal decomposition effects and the association constants were determined. Laboratory samples of sensors of different structures and composition were manufactured and tested and their composition was optimized. For the first time the connection between the lower detection limit temperature sensor and the beginning of thermal degradation of the studied ion associates was determined. Laboratory samples of platicized membrane and soli-contact potentiometic sensors were developed for the determination was various forms of iodine, organic peroxocompounds, ascorbic acid, sodium sulphite, sodium metamizole and pentachloro¬phenole. New methods of potentiometric determination suitable for the analysis of natural and biological objects, foodstuffs, pharmaceuticals were developed. The developed methods are suitable for use in factory and clinical laboratories, laboratory quality control of pharmaceuticals and food products.
