Abstract: Modified biochar prepared by ball milling mechanochemical technology has been widely
concerned by researchers in recent years due to its many advantages, such as low cost, high productivity,
green and solvent-free. Ball milling modification can increase the surface functional groups, expand the
specific surface area and improve the adsorption capacity, which makes biochar have excellent removal
performance for environmental pollutants and broad application prospect in the field of environmental
remediation. The preparation and physicochemical properties of ball milling modified biochar are
introduced. The latest progress of ball milling modified biochar in the removal of pollutants in environmental
remediation is summarized. The removal mechanism of ball milling modified biochar for various pollutants
is defined. On this basis, the existing problems and limiting factors of ball milling modified biochar in
environmental remediation are discussed. The future research directions are put forward from the aspects of
clarifying the technical and economic feasibility, expanding the application scope of materials, clarifying
the potential ecological and environmental risks.
