Characterization of Silica Gel Impregnated with Tetradecylamine by X-Ray Diffractometry and Brunauer-Emmet-Teller Studies

Abstract:

Commercially available porous silica gel (SG) is chemically modified for carbon dioxide capture. Calcinated silica gel functionalized with amine (tetradecylamine, TDA) using wet impregnation has been employed as a porous media. The prepared adsorbents is characterized by x-ray diffractometry (XRD) and N₂ physisorption techniques (Brunauer-Emmet-Teller analysis, BET). Appearance of 3 new crystalline peaks on 65TDA/SG diffractogram evidenced the presence of TDA molecules on the SG. Significant changes in physical properties of the adsorbents further ascertained the dispersion of TDA on the internal channels and external surface of the SG.
