Study of the Adsorption Properties of Lanthanum-Doped Mesoporous Silica Gels, Modified with Nickel and Silver, by the Method of Gas Chromatography
— The adsorption properties of the lanthanum-doped mesoporous silica gel modified with nickel and silver (La–Ni/MC, La–Ag/MC) synthesized by the template method were studied by gas chromatography. The textural characteristics of the obtained materials were studied by the methods of low-temperature n...

| description | —
The adsorption properties of the lanthanum-doped mesoporous silica gel modified with nickel and silver (La–Ni/MC, La–Ag/MC) synthesized by the template method were studied by gas chromatography. The textural characteristics of the obtained materials were studied by the methods of low-temperature nitrogen adsorption-desorption, atomic emission spectroscopy (ICP), X-ray phase analysis (XRD), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM). The thermodynamic characteristics of adsorption (differential heats and entropies) of test organic compounds were obtained by the inverse gas chromatography. It has been established that doping and modification leads to changes in the heats of adsorption for compounds prone to various types of specific interactions. It is shown that mesoporous silica gel doped with lanthanum and modified with nickel exhibits more pronounced adsorption properties with respect to the studied sorbates. |
