摘要

随着全球工业化进程的加快，重金属污染已成为威胁生态环境和人类健康的重要问题。生物炭作为一种源自生物质热解的环境友好型材料，因具有丰富的孔隙结构和表面官能团，在重金属污染修复中展现出巨大潜力。然而，原始生物炭的吸附能力受限于比表面积不足、活性位点单一等问题，通过氯化镁改性可显著提升其吸附性能。综述了氯化镁改性生物炭的制备工艺、吸附机制、关键影响因素及环境应用，结合最新研究成果，分析当前技术瓶颈并展望未来发展方向，为未来重金属污染治理提供理论支撑和技术参考。

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
