Sol-Gel Synthesis of Chelate Containing Materials for Gas Chromatography

Article Preview

Abstract:

The adsorption properties of mesoporous chelate containing sorbents which were prepared in two phases with europium and copper acetylacetonate complexes and PEG-115 as surfactant, were evaluated by column experiments.The adsorption properties of mesoporous silica with chelate complexes for some organic compounds were evaluated by gas chromatography. The best separation was achieved for europium acetylacetonate. From specific retention volumes measured at various temperatures the thermodynamic parameters of separation is discussed. Mutual separation of oxygen containing substances could also be demonstrated.
