Preconcentration of Organic Substances on Low-Polar Adsorbents in the Flow Systems of Analysis

详细

A review of works performed by the authors and devoted to the development of new approaches to the preconcentration of organic compounds (phenols, phthalates, polycyclic aromatic hydrocarbons, and other toxic substances) on low-polar adsorbents is presented. Possibilities of the application of calculation methods to the selection of effective adsorbents and optimal concentration conditions and to the prediction of the behavior of analytes in flow adsorption chromatography systems of analysis are discussed. New methods of the adsorption preconcentration of analytes on fluoroplastic and carbon adsorbents, including the use of subcritical water for desorption, are proposed. A short list of procedures developed for water analysis using these preconcentration methods is presented.
