Abstract
Water contamination with toxic substances is considered to be a crucial environmental and health issue globally. Treatment and recycling of contaminated water is essential to overcome water quality and availability related problems. Various conventional technologies (such as coagulation/flocculation, membrane separation, lime softening), used to treat wastewater have numerous limitations, including less removal potential, high cost, operational needs and high waste generation, which promotes secondary pollution. Biochar has drawn significant attention in recent years due to its remarkable adsorption capacity for various pollutants. However, separation of spent biochar from water contributes to generation of secondary pollution (biochar-sludge) and may impede biochar usage on a wide scale. Incorporation of magnetic medium (e.g., hematite (Fe2O3), magnetite (Fe3O4) and zero valentiron (Fe)) into biochar matrix fabricates a conveniently separable magnetic biochar (MBC) that has been seen as a key technique to overcome the abovementioned problems. This chapter is focused on fabrication techniques of MBC, physiochemical properties, characterization methods, adsorption mechanisms, and removal of organic, inorganic, and nuclear waste pollutants and reuse potential of MBC. The current knowledge gaps and future recommendations to improve usage of the MBC for wastewater treatment are also discussed.
