Abstract.

Bonded phase ODS-silica has been prepared using purified silica prepared from rice husk by burning, reflux with sodium hydroxide solution and precipitation as a gel. The gel was spray dried, further purified by washing with concentrated hydrochloric acid then distilled water prior to vacuum drying and silanization and end-capping. The product’s physical and chromatographic properties are reported.
