- DEVELOPMENT OF ACTIVATED CARBON FROM BAMBOO (Bambusa vulgaris) FOR PESTICIDE REMOVAL FROM AQUEOUS SOLUTIONS Gregório Mateus Santana Roberto Carlos Costa Lelis Emerson Freitas Jaguaribe Rayssa de Medeiros Morais Juarez Benigno Paes Paulo Fernando Trugilho Agrociencias Forest products water treatment adsorbent development Considering the water scarcity problems facing many countries, the need for water reuse can make activated carbon (AC) an essential product for modern society. In this context, to contribute with better activated carbons that could be used to serve in water treatment, this article discusses these materials production, using bamboo as raw material, and analyses their application effectiveness. The bamboo was collected, transformed into activated carbon, by simultaneous chemical and physical activations, and named H 3 PO 4 / H 2 OAC. The obtained material was characterized by its yield, apparent density, ash content, thermogravimetric analysis, surface area, methylene blue and iodine indexes, pH and point of zero charge analysis, scanning electron microscopy and Boehm titration method. The AC was used as adsorbent for removing the metribuzin, 2,4-dichlorophenoxyacetic acid and furadan pesticides. The H 3 PO 4 /H 2 OAC had a surface area of 1196.30 m² . g -1 and the obtained adsorption capacity was elevated for furadan (868.98 mg . g -1 ), metribuzin (756.47 mg . g -1 ) and 2,4-dichlorophenoxyacetic acid (274.70 mg . g -1 ). 2017 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74450574014 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.1 Vol.23
