Zybak I. Physico-chemical interaction of carbon oxides and hydrocarbons with cationes Ag+ and Cu2+ in zeolites M, X and Y

The dissertation summes up systematic investigations of more than 35 modifications of zeolites NaX, NaY and NaM with binding clay whose Na+-cationes (up to 10%) are replaced by Ag+ or Cu2+. All the samples are studied by the gas chromatographic method in the temperature range 293-573 K. We calculate thermodynamic and chromatographic parameters of interaction of gases of various nature with cationes in zeolites. On modifications CuNaX and CuNaY we confirm the effect of low substitution. Move over on Ag- and Cu-mordenites this effect is discovered for the first time and its quantitative degree is estimated. We reveal the effect of nivelatively action of adsorbed water on thermodynamic and chromatographic characteristics of gas adsorption on hydrated zeolites. Applyivy the obtained datas we recommend optimal zeolite modifications and optimal conditions for concentrating and chromatographic analysis of many pollutants from the air.
