Karazin popup.description2 Object of investigation - processes of complex formation of ions of metals with PAN in aqua-micelles media, equilibria of exchange reactions on 8-hydroxyhynoline in complexes, for ultrasound of high and low frequencies, determination of toxicants impurities in the many component systems, deoxidation process, based on mixed halogenates of potassium and strontium from oxygen containing impurities by gas like halogenated agents, single crystals, based on mixed halogenates of potassium and strontium, activated by Europeum. Subject of investigation - synthesis of d-metals ions with PAN complexes, burden for single crystals growth, based on mixed bromides of potassium and strontium, intensification of chemical-analytical and chemical-technological processes, acidic properties of ionic halogen alloys based on strontium chloride, process of carbobromation of KSr2Br5 alloy, process of growth of K2SrCl4 : Eu2+ single crystals. The purpose of the investigation - development of apparatus of many component spectrophotometric determination of ions of metals by two dimension spectra of its complexes with PAN, elaboration of theoretical bases to use ultrasound for generation of analytic signal and intensification of sample preparation ways and medias to extract analysts from many component systems, development of single crystals growth methodic, based on mixed chlorides of potassium and strontium, activated by Europeum, and deoxidation of burden for single crystals synthesis. Methods - spectrophotometry, titrimetry, potentiometry, extraction, linear-algebraic methods to treat the results of measurements, atomic-absorption and atomic-emission spectroscopy with inductive connected plasma, ultrasound treatment, sonoluminiscent spectroscopy, carbohalogenation, Bridgement-Stockbarger method, luminescent, spectral-kinetic. Obtained results and their novelty: - the exchange process of PAN on 8-hydroxyhynoline for d-elements chelates in water-micelles media was studied for the first time; - it was shown that complex four component ions mixtures can be analyzed by these properties; - an accuracy, precision, expresses of analysts determination in many component systems was supplied; - the method to determine quantitative of absorption sound chemical energy of ultrasound in sodium chlorine and cooking salt solutions was developed for the first time; - the mechanism of influence of ultrasound on processes of destruction and dissolution of complex organic compounds in inorganic salts was proposed for the first time; - the solubility product of magnesium oxide in KSrCl5 alloy at 973 К was determined for the first time; - it was shown that large oxide-ions, contains Sr2+, are exists like complexes Sr3O4+ or 2SrCl2·SrO; - it was shown at first that KSr2Cl5 alloy may be purified up to рО = 6,78 by carbohalogenation; - rate constant of the process at 973 as 1,8·105 kg·mol-1·min-1 was estimated for the first time; - the methodic to obtain burden for single crystals growth, based on mixed bromides of potassium and strontium was worked out for the first time; - the project of the methodic of growth of the single crystals, based on mixed chlorides of potassium and strontium, activated by Europeum was developed; luminescent properties of the single crystals samples was investigated for the first time.
