XRD and CO2 adsorption studies of modified silica gel with octadecylamine
Porous surface of silica gel (SG) have been modified with long and straight chain fatty amine compounds (octadecylamine, ODA) via wet impregnation process. Initially, heat treatment with various temperature which are 100 ºC, 200 ºC, 400 ºC and 600 ºC was done to the SG before continuing with impregn...

| description | Porous surface of silica gel (SG) have been modified with long and straight chain fatty amine compounds (octadecylamine, ODA) via wet impregnation process. Initially, heat treatment with various temperature which are 100 ºC, 200 ºC, 400 ºC and 600 ºC was done to the SG before continuing with impregnation process. Characterizations by XRD of the treated samples were showed no significant difference in each diffractogram. The best temperature for heat treatment was 600 ºC (SG600) and it was referred to the ability of the SG600 type adsorbents in adsorbing CO2 resulted from adsorption desorption isotherm of CO2. The 5 and 35 wt% of ODA supported on the SG600 was further characterized using XRD analysis which displayed the increasing intensity of crystalline ODA with higher percent amine loaded and shifting of the several crystalline peaks of ODA verified the interaction of SG600-ODA. These further strengthen the dispersion of ODA on the surface of SG600. |
