Solvent Recovery of Silica Aerogel Monoliths Synthesis and Adsorption of Trivalent Chromium Ions

Abstract:

SiO₂ aerogel monoliths were prepared at ambient pressure by keeping the volume ratio of TEOS: EtOH: Oxalic acid at 1:0.6:0.2 with sol-gel method. The prepared aerogels were characterized by scanning electron microscope (SEM), and Brunauer-Emmett-Teller method (BET).The result indicated that silica aerogel monoliths synthesized via these conditions had a excellent structure and fascinating properties (bulk density of 0.254 g/cm³, specific surface area of 770.5 m²/g). Deionized water and calcium chloride anhydrous were used to recover n-hexane to reduce the cost of aerogel synthesis. The purity of recycled n-hexane could reach up to 98.5%.The uptaken rate of Cr³⁺ by aerogels was as high as 99.25% with the pH of 6.86, adsorption time of 20h.
