Antibiotics have been used in massive quantities for human and animal medical treatment, and antibiotic resistance genes (ARGs) are of great concern worldwide. Antibiotics and ARGs are exposed to the natural environment through the discharge of medical wastewater, causing great harm to the environment and human health. Biochar has been widely used as a green and efficient adsorbent to remove pollutants. However, pristine and unmodified biochars are not considered sufficient and efficient to cope with the current serious water pollution. Therefore, researchers have chosen to improve the adsorption capacity of biochar through different modification methods. To have a better understanding of the application of modified biochar, this review summarizes the biochar modification methods and their performance, particularly, molecular imprinting and biochar aging are outlined as new modification methods, influencing factors of biochar and modified biochar in adsorption of antibiotics and ARGs and adsorption mechanisms, wherein adsorption mechanism of ARGs on biochar is found to be different than that of antibiotics. After that, the directions of biochar and modified biochar worthy of research and the issues that need attention are proposed. It can be noted that under the current dual carbon policy, biochar may have wider application prospects in future.
抗生素被大量用于人类和动物的医疗治疗，抗生素抗性基因（ARGs）在全球范围内引起了极大的关注。抗生素和 ARGs 通过医疗废水的排放而暴露于自然环境中，对环境和人类健康造成了巨大的危害。生物炭已被广泛用作一种绿色高效的吸附剂来去除污染物。然而，原始的未经修饰的生物炭被认为不足以应对当前严重的水污染。因此，研究人员选择通过不同的改性方法来提高生物炭的吸附能力。为了更好地了解改性生物炭的应用，本综述总结了生物炭的改性方法及其性能，特别概述了分子印迹和生物炭老化作为新的改性方法，以及生物炭和改性生物炭在吸附抗生素和 ARGs 方面的影响因素和吸附机制，其中发现 ARGs 吸附在生物炭上的机制不同于抗生素。之后，提出了生物炭和改性生物炭值得研究的方向以及需要注意的问题。值得注意的是，在当前的双碳政策下，生物炭在未来可能具有更广泛的应用前景。
