Betung Bamboo-Based Magnetic Biochar for Dye Removal

Abstract

Water is one of the vital resources of human life. The rapid development of the industrial sector in developing countries is one of the main factors that contribute to water pollution, due to a lack of environmental awareness. Therefore, it is very important to remove the pollutants from industrial wastewater before being discharged into water bodies. Adsorption using inexpensive and high availability materials such as magnetic biochar is a promising alternative. Embedding magnetite (Fe3O4) into biochar not only aims to solve the separating problem, but also to strengthen the adsorption performance of the biochar. This book chapter introduces the preparation and characterization of magnetic biochar derived from betung bamboo. Furthermore, a discussion was conducted to provide a perspective on the use of magnetic biochar in adsorption technology, particularly in the removal of dyes in an aqueous solution. Finally, the isotherm models for the magnetic biochar-dye system are discussed at the end of this chapter.
