摘要：
Herbicides have been used extensively in modern agricultural production, but the long-term application of herbicides has resulted in a large amount of residues in the soil, which pollutes water through precipitation, leaching and runoff, thus causing environmental pollution and food safety issues. Biochar, as a kind of green and efficient adsorbent, has been widely used for the remediation of organic-polluted water and soil. This review summarized the modification methods of biochar, such as acid-base, organic matter, and metal salt dipping, nano zero-valent iron and microbial load modification. The application of modified biochar in the remediation of herbicide pollution was introduced, and the remediation effects of pristine and modified biochar were compared and analyzed. The effects of modified biochar characteristics and environmental conditions on the remediation of herbicide pollution and their mechanism were discussed. In the future, the stability, long-term performance, and safety of modified biochar in the remediation process of herbicide pollution still need to be explored. © 2024 Chemical Industry Press Co., Ltd..
