[ 1 ] - Synthesis and Characterization of Waterglass-Based Silica Aerogel Under Heat Treatment for Adsorption of Nitrate from Water: Batch and Column Studies

In this work, hydrophobic silica aerogels were synthesized using sol-gel method and drying at ambient pressure. The surface morphology, pore size, and the presence of functional groups on the surface of the nanoparticles were analyzed using FE-SEM, TGA, FT-IR, and EDX, respectively. After calcination at 500 °C, the hydrophilic property of the adsorbents was evaluated by water contact angle meas...
