Abstract

With the acceleration of global industrialization, heavy metal pollution has become an important issue threatening the ecological environment and human health. Biochar, as an environmentally friendly material derived from biomass pyrolysis, has great potential in heavy metal pollution remediation due to its rich pore structure and surface functional groups. However, the adsorption capacity of primitive biochar is limited by issues such as insufficient specific surface area and single active sites. Modification with magnesium chloride can significantly improve its adsorption performance. The preparation process, adsorption mechanism, key influencing factors, and environmental applications of magnesium chloride modified biochar were reviewed. Combining the latest research results, the current technological bottlenecks were analyzed and the future development directions, providing theoretical support and technical references for the treatment of heavy metal pollution in the future were looked forward.

Key words： magnesium chloride modified biochar adsorbent heavy metals pollution control
