Resumo
We have synthesized silica-based sorbents with MCM-41 and MCM-48 pore structures, modified with hydrazide groups based on tret-carboxylic acids of Versatic 10 and Versatic 1519 fractions, and investigated textural and structural properties of the silicas. Conditions for tungsten(VI) sorption from acid solutions by the silicas have been studied in relation to the pH of the medium and grafting density, and conditions have been found for tungsten(VI) and molybdenum(VI) separation from hydrochloric acid solutions using MCM-41 modified silica.
