| Abstract: | A simple and low-cost process has been developed for the production of mesoporous silica microspheres using a non-ionic surfactant
as a template in an aqueous acidic sodium silicate solution prepared from rice husk. The influences of synthesis parameters
such as the sodium silicate concentration, hydrochloric acid concentration, temperature and aging time on the morphology and
on particle size range are described. The product’s physical and normal phase chromatographic properties are reported. |
