Molnar D. Extraction and analytical application of ionic association of nickel (II) and cobalt(II) with nitrosonaphthols and cyanine dyes

Object of investigation: ionic association of Ni (II) Co (II) with cyanine dyes. Aim of investigation: investigation of general properties and peculiarities of complex- and IA-formation of iones Ni (II) and Co(II) with nitrosonaphthols and cyahihe dyes. Methods of investigation: preparation chemistry, electronic and IR spectroscopy, potentiometry, radiochemistry and AAC. Theoretical and practical results, novelty: the dissertation is devoted to the investigation of general properties and peculiarities of complex- and IA- formation of iones nickel (II) and cobalt(II) with nitrosonaphthols and cyanine dyes. The optimal condation for extractive-photometric determination of iones Ni(II) and Co(II) as an ionic association with show reagents has been findes. Have been carried out selection extragents and studied influence pH, character and concentration dye - stuff, acid and nitrosonaphthols. Issue from electronic spectrum calculated the main chemical-analytical characteristics of ionic association nickel and cobalt with cyanine dyes. The high effectiveness of the methods is staded by using of theoretical investigations and reinforced by the patent. The highly reliable extraction-photometric methods have been developed for determination of Ni and Co in semiconductor, and chemical materials, enviromental objects. Degree of application: teaching of special curs "Organic reagents in analytical chemistry" " Complex compounds in analytical chemistry" Field of application: analytical chemistry.
