摘要

New packings based on Silochrome C80 modified with Cu(II), Co(II) and Ni(II) 8-oxyquinolinates were studied. Their sorption characteristics and chromatographic properties were investigated and the comparative evaluation of sorbents polarity was carried out by applying Rohrschneider-McReynolds coefficients system, thermodynamic data and using the solvation parameter model of Abraham. It was found that the nature of metal and complex structure have a decisive influence on the physico-chemical properties of the packings. Modified silica gels show high selectivity for gas chromatographic separation of oxygen containing and aromatic organic compounds.
