  • Hydrophobic silica aerogels - solvent removal from water [Elektronski vir]
    Novak, Zoran ; Štandeker, Suzana ; Knez, Željko
    Hydrophobic silica monolith aerogels were prepared by incorporating methyltrimethoxysilane (MTMS) in standard sol-gel synthesis following by drying of gels in supercritical CO2 at 40 °C. The ... hydrophobicity of aerogels was tested by measuring the contact angle. Adsorption capacity measurements show that hydrophobic silica aerogels are excellent adsorbents for different toxic organic compounds from water. In comparison to granulated active carbon (GAC) they exhibit capacities which are more than 70 times higher for all tested compounds.
