Mesoporous Spherical Shaped Silica Nanoparticles for the Effective Adsorption of Aqueous Lead (Pb²⁺)

Fabrication of Mesoporous Silica Nanoparticle-Decorated Graphene Oxide Sheets for the Effective Removal of Lead (Pb2+) from Water

“…Mesoporous uniform-sized silica nanoparticles (MSiO 2 NPs) were synthesized by hydrolysis of TEOS in water−ethanol emulsion medium along with the ammonium hydroxide as reported in our earlier work. 18 First, 30 mL of water−ethanol medium (10 mL of water + 20 mL of ethanol) was kept for 30 min in an ultrasonication bath. Simultaneously, 10 mL of TEOS was added dropwise to the ultrasonication process.…”

“…The consequence of varying doses (5−50 μg mL −1 ) of MSiO 2 /MSiO 2 -GO nanosheets on the cells' morphology was determined as described in detail elsewhere. 18 Treatment of cells was done separately using 40 μg mL −1 MSiO 2 and MSiO 2 -GO nanosheets. Subsequently, after 24 h, the medium was discarded from each well and then kept for 20 min shaking speed = 200 rpm for 1 h).…”
