Adsorption properties of silica modified by stab le palladium nanoparticles on gas chromatography data

Abstract

Palladium nanoparticles have been synthesized in reverse micelles by radiation-chemical method
with different molar ratio of H2O to AOT. The adsorption of palladium nanoparticles has been carried out
on silica S-120 surfaces. The adsorption properties of nanocomposits, containing Pd nanoparticles has
been studied by gas chromatography methods. It has been established that the modification of the surface
of C-120 by Pd nanoparticles does not change Henry constant of adsorption equilibrium K1,C for n –
hydrocarbons, in case of polar compounds K1,C depends on the size and structure of Pd nanoparticles,
which can be varied by changing water content of reverse micelles taking different values of ω0.
