ADSORPTION PROPERTIES OF TITANIA-SILICA MEMBRANES OBTAINED ON CERAMIC SUBSTRАTE

Adsorption of hidrogen peroxide on the surface of silica – titania mixed oxide obtained by the sol-gel processing method

This work describes the sol-gel mixed oxide SiO 2 /TiO 2 property, ST, as prepared, and submitted to heat treatment a 773 K, STC. SEM and EDS images show, within magnification used, a uniform distribution of the TiO 2 particles in SiO 2 /TiO 2 matrix. Both, ST and STC adsorb hydrogen peroxide on the surface and through EPR and UV-Vis diffuse reflectance spectra, it was possible to conclude that...

Adsorption Properties of Thiol-Functionalized Silica Nanoparticles Prepared for Application in Poly(ether sulfone) Nanocomposite Membranes

Chromatographic Characterization of Adsorption Properties of Carbon and Silica Adsorbents

Adsorption isotherms and specific retention volumes of benzene on MCM41C16 mesoporous silica and F4O porous carbon were determined at different temperatures by employing inverse gas chromatography. The differential isosteric enthalpies, -∆Hads , and entropies, -∆Sads , of adsorption were calculated from the retention time data and compared with the results obtained from the adsorption second vi...
