Адсорбционные свойства поверхности силикагеля с привитыми слоями хелатов переходных металлов

Abstract

Studied the adsorption properties of the surface Silipor 200 and chemically modified on the basis of its sorption materials containing acetylacetonates, ethylacetoacetate, malonates of nickel. As test compounds were used n-alkanes (C6-C9) and the adsorbates whose molecules have different electron-withdrawing and electron donating properties. From the experimental data on the retention of adsorbates designed their differential molar heat of adsorption q̅ dif, 1, change the standard differential molar entropy ΔS̅ S1, C and for polar adsorbates contributions Δ q̅dif,1(spec) for energy dispersive and specific interactions.
