In the last few decades, there has been enormous research carried out on biochar for the removal of contaminants from wastewater or soil. e.g., organic and inorganic contaminants, metals.” BIOCHAR” is defined by its physical and chemical properties. This review aims to highlight the applications of biochar's in wastewater and soil, including a quick view of the mechanism of sorption of the metals and modified biochar. Depending on the types of biochar metals are removed via various mechanisms like exchange of ions, complexation, physical sorption, precipitation, and electrostatic interactions. It also provides information about the potential of biochar in the remediation of soil and also summarizes the removal of dyes from the wastewater by recent advances such as adsorption and catalysis. Overall, further studies are required to reuse biochar.
