摘要

以温度变化和十六烷基三甲基溴化铵浓度为原料，研究了以稻壳为原料制备介孔二氧化硅的硅官能团。本研究采用CTAB浓度分别为2.0%、2.5%、3.0%、3.5%的碱法合成稻壳二氧化硅，并在120、130、145、160℃的温度下在高压釜中进行1小时的水热处理。傅里叶变换红外(FTIR)结果表明，Si-O-Si以及C-H、-H、O-H和-OH等基团是最主要的星团。因此，硅基稻壳可以作为介孔二氧化硅的原料

Pengujian Gugus Fungsi Silika Berbasis Sekam Padi Dengan Variasi Suhu & Konsentrasi Cetyltrimethylammonium Bromide Sebagai Bahan Baku Mesoporous Silica

Research has been conducted to test silica function groups based on rice husks with temperature variations and concentrations of Cetyltrimethylammonium Bromide as raw materials for mesoporous silica. In this study, rice husk silica was synthesized by alkaline method with variations in CTAB concentrations of 2.0%, 2.5%, 3.0%, 3.5%, and hydrothermal treatments with temperature variations of 120, 130, 145, and 160ºC for 1 hour in an autoclave. Fourier-Transform Infrared (FTIR) results showed the presence of the most dominant clusters, namely Si-O-Si and other groups such as C-H, -H, O-H, and –OH. Therefore, silica-based rice husks can be used as raw materials mesoporous silica
