Abstract
The results of measurements of adsorption and structural characteristics of ASD-6 powder modified with vanadium pentoxide in different concentrations are presented; the specific surface area and porosity of the powders were calculated. With a 5% vanadium pentoxide addition, the specific surface area of ASD-6 + 5%V2O5 increased more than fivefold, and the porosity amounted to 0.036895 cm3/g at an average pore width of 8.2686 nm, whereas pure ASD-6 has a specific surface area of 1.1388 m2/g. Taking into account the data on the specific surface area, porosity, and the results of physicochemical analysis, optimal concentrations of vanadium hydrogel have been proposed, which make it possible to obtain dispersed systems with the required properties.
