Abstract


Now, water pollution is one of the leading concerns in the world especially heavy metal polltion. In recent years, researches on the use of agricultural waste as biochar and modified biochar to treat heavy metals in water are receiving the attention of scientists because of the economy as well as the high processing efficiency that it brings. In this study, biochar from rice husk was synthesized and modified by iron, then the obtained materials were characterized by SEM, FTIR methods. The results show that the Fe-biochar shows a high potential to remove arsenic at pH = 4 and the adsorption capacity was 18,96 – 28,49 mg/g.

Keywords
