WebThen, SBA-15 was acquired by calcining the solid in air at 550 C for 6 h. 2.3. Synthesis of the Amino-Functionalized SBA-15 Specimens Using a reflux apparatus, 2.0 g of SBA-15 and 2.0 g of APTES were mixed in 60 mL of anhydrous alcohol at 78 C for 24 h [24]. The sediment was repeatedly rinsed with ethanol, and then dried in a vacuum oven at 60 ... Webremove Azure B dye by SBA-15, the optimal values were obtained as the parameters of contact time = 30 min, pH = 8, temperature = 65 °C, adsorbent amount = 0.01 g, stirring rate = 90 rpm and initial dye concentration = 100 mg/L. The kinetic and thermodynamic experiments were conducted on the adsorption process as well. WebAmine-functionalized SBA-15 andMCM-41werepreparedbypost-synthetic grafting. An aliquot of APTMS, MAPTMS, or DMAPTMS (87, 99, and 109 μl for 0.5 mmol, respectively) was added to 1 g of cal-cined SBA-15 or MCM-41 in 100 ml of anhydrous toluene under argon. This mixture was stirred overnight in a closed container at room tempera-ture. orchid containers hone depot
