Extraction of gelatin from bovine bone and its application as a template for synthesis of mesoporous silica have been studied. The bone was pretreated with acetic acid 4 % for 9 days, followed by sodium hydroxide 0.1 M for 24 h and hydrochloric acid 1 M for 1 h. The pretreated bovine bone was then refluxed in demineralized water for 5 h at 70, 80, 90 and 100 °C to extract gelatin. The gelatin was analyzed by FTIR and SDS-PAGE. The synthesis of mesoporous silica was performed by hydrothermal method. The product was analyzed by FT-IR, XRD, nitrogen gas adsorption and TEM. The result showed that the gelatin extracted at 80, 90 and 100 °C contained ? and ?-chains. However, the gelatin extracted at 70 °C contained only ?-chains. The silica had pore diameter, specific surface area and pore volume of 6.08 nm, 384.21 m2/g and 0.75 cm3/g, respectively. The silica had wormhole-like mesoporous structure. |
