Silica is found in many agricultural by-products, with some having a significant amount of silica in their matrix. Burning the material, followed by treating it with a chemical or acid-based solution, can be used to separate the silica from the matrix. The rice husk ionic liquid can be used to extract silica nanoparticles as well.
