Using Rice Husks in Water Purification in Brazil

Research output: Contribution to journalArticle


Rice husk, which considered a waste, has a high level of silicon. This paper investigates the use of carbonized rice husk in water purification. The carbonization was done using a handmade carbonizer. The preparation process starts with the production of a precursor that is rich in carbon through the pyrolysis of the rice husk in an inert atmosphere. The results show an important contribution of the use of carbonic materials, by giving a direct evidence of the permanence of sodium ion Na+ in activated carbon. The results also show that the utilization of carbonized rice husks in the purification of water is quick, efficient and economically viable.
