Аннотация:A method was proposed for preconcentrating small amounts of numerous organic contaminants. The method is based on supercritical fluid extraction and trapping the extracted compounds with a multilayer adsorption device followed by their thermodesorption directly to a gas chromatographic system. A method was described for preparing stabilized adsorbents on the basis of a support with a stationary phase using sol-gel synthesis.
