Abstract |
|
|
| Rice husk (RH) is an agricultural solid waste residue. It is a byproduct in rice mills and creates disposal and pollution problems. Burning of RH in ambient atmosphere causes toxic air pollution also dumping causing damage to the land and the surrounding area in which it is dumped. Therefore RH and rice husk ash (RHA) must be appropriately managed. In the present article synthesis methods for silica from RHA are reviewed. In addition basic properties, structure and uses in various industries of RH, RHA and silica have been lighted. |
