Alkali Metal Modification of Silica Gel-Based Stationary Phase in Gas Chromatography
Modification of the precipitated silica gel was done by treatment with alkali metal (NaCl) before and after calcination. The silica surfaces before and after modification were confirmed by infrared spectroscopy in order to observe the strength and abundance of the acidic surface OH group bands which...
