In this paper, a simple immobilization of β-cyclodextrin (β-CD) on silica from rice husk ash is reported. Silica isolated from rice husk ash is chlorinated with 3-(chloropropyl)triethoxysilane (CPTES) for the attachment of chlorine group on the surface of silica via a simple sol-gel technique. Immobilization of β-CD with modified silica has been performed using the mixing process. The confirmation of β-CD binding onto the surface of modified silica has been done by FTIR, SEM, and EDX analysis. This immobilized preparation can be used for the immobilization of enzyme as well as in the adsorption of aromatic pollutants present in the wastewater in the future.
