MODIFIKASI SILIKA GEL DENGAN METODE GRAFTING DAN APLIKASINYA SEBAGAI FASE DIAM PADA KOLOM KROMATOGRAFI
The preparation of octadecylsilica (ODS) by the grafting method as stationary phase of cromatography column has been investigated. The stationary phase was used to simulate the separation of a mixture containing benzene, toluene, naphthalene, and to determine the concentration of ascorbic acid in so...

description |
The preparation of octadecylsilica (ODS) by the grafting method as
stationary phase of cromatography column has been investigated. The stationary phase was used to simulate the separation of a mixture containing benzene, toluene, naphthalene, and to determine the concentration of ascorbic acid in soft drinks.
This study began with the activation of silica gel using 20% HCl (v/v).
Calcination was performed at 200, 300, 400 and 450 °C for 4 hours followed by modification with n-octadecyltriethoxysilane (ODTS) as bonded phase.
Characterization of ODS showed a decrease in surface area, pore volume, pore radius. Strong infrared absorption at 2931.80 cm-1 and 2854.65 cm-1 indicates asymmetric and symmetric streching vibrations of methylene group, respectively. The optimum conditions obtained by calcination 300 °C with surface area, pore volume and pore radius of 281.82 m2/g |
