Yurchenko O. Metal beta-diketonates as analytical forms and basis of standard samples for spectroscopic analysis

Object of investigation: influence of the properties of standard samples on the characteristics of the spectroscopic analytical methods. Aim of investigation: Improving quality of the spectroscopic analysis via design and introduction of the polyfunctional standard samples on the base of metals beta-diketonates and enlarging of the area of beta-diketones application for qualitative and quantitative detection of organic and inorganic analytes. Methods of investigation: elemental analysis, cryometry, flame atomic absorption (AA) spectrometry, non-flame atomic absorption spectrometry of the cold vapors, spectrophotometry, AES-ICP, roentgen-fluorescent analysis, emissive spectral analysis. Theoretical and applied results: The new direction in the analytical chemistry of standard samples was developed. It consists of the developing backgrounds and theoretical justification of the application of the metals beta-diketonates in the chemical analysis as the starting materials for design of the standard samples. Science novelty: Design and practical application of polyfunctional standard samples based on the metals beta-diketonates allows to increase the expressness of analysis, to improve the metrological characteristics and ecological safety of the methods of metals detection in the polycomponent samples of various origin, to exclude the necessity to apply complicated analytical methods for the massive analysis. Degree and field of the practical application: Accuracy and precision of spectroscopic methods of analysis were enhanced due to the application of the polyfunctional standard samples and surface-active compounds. Analytical procedures to determine microquantities of metals in raw materials, industrial waste waters, standard samples of non-ferrous metals and alloys, air, food and petrol staffs based on the metals beta-diketonates as standard samples and surface-active compounds as modifiers were elaborated and applied in industry and other fields.
