“…The experiments were conducted by mixing the nanocomposite as photocatalyst and RBB in a certain catalyst dosage (0.4 g). The photodegradation test was carried out using three varaiation condition, namely pH (1,3,5,7,9,11), initial concentration of RBB solution (2,4,6,8,10,20,30,40,50,100,200, 300, 400, 500 mg/L), and contact time (5,10,15,20,30,40,50,60,120,180, 240 minutes). The suspended solid was filtered and the filtrate was analyzed to determine methyl violet concentration using a UV-visible Spectrophotometer (Model Genesys 10 uv, Thermo Scientific, USA) at wavelength (max) of 592 nm.…”

“…In addition, azo dyes are toxic and carcinogenic which can threaten the life of living things [3]. Thus far, several studies have been initiated to remove the dyes from wastewater, including electrocoagulation [4], osmosis [5], aerobic process [6], anaerobic process [7], and adsorption [8][9][10][11][12][13]. Among these methods, adsorption is the most widely used method due to its simple design and high efficiency [14].…”

This work implicates the synthesis of biochar-hematite nanocomposite from bamboo sawdust and its photodegradation characteristic for remazol brilliant blue. The nanocomposite was prepared through a one-step pyrolysis process in a tubular furnace under a flow of nitrogen and impregnation using FeSO4.7H2O and FeCl3.6H2O. The physicochemical properties were characterized by x-ray diffraction and Fourier transform infrared spectroscopy, which confirmed that hematite was successfully identified on the surface of the nanocomposite. The results also show that the nanocomposite is suitable for photodegradation application. The decolorization of remazol brilliant blue is suitable with the Langmuir isotherm model and pseudo-second-order kinetic model. At pH = 1, initial concentration = 200 mg/L, contact time = 60 minute and nanocomposite dosage 0.4 g/L, the decolorization efficiency reached 96.9%.

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.
