Abstract :Today, various methods are used to remove the dye pollution in the increasing water. Adsorption is a fast and effective method that has been used since the past. The value of the obtained adsorption capacity varies according to the type of biosorbent material used. The seeds of the fruit of Sophora Japonica insert ignore into journalissuearticles values(SJfs);, a tree commonly found in nature, were pyrolyzed at 450°C to produce biochar insert ignore into journalissuearticles values(SJfsB); in this study. Iron nanoparticles were immobilized into the SJfsB structure to form a more active biosorbent matrix. The obtained SJfsB and nM-SJfsB were used in the removal of methyl blue, an anionic dye. SJfsB and nM-SJfsB used for dye removal were characterized by FT-IR and SEM instruments. The obtained results revealed that the adsorption process occurred in the pseudo-second-order and was consistent with the Langmuir model. The maximum adsorption capacity for MB removal was 434.783 mg/g for nM-SJfsB and 76.923 mg/g for SJfsB, respectively.
