摘要
在多种环境介质中频繁检测到的环丙沙星(CIP)等抗生素,因其对人类健康和生态的潜在风险,对其进行高效去除已成为研究的热点。生物炭(BC),作为一种经济且高效的吸附剂,因其成本较低、卓越的吸附性能以及良好的再生能力,在抗生素的去除过程中显示出广泛的应用前景。由于BC对抗生素的吸附能力存在局限性,使其难以在实践中应用,因此,有必要对BC进一步改性。本文总结了BC的制备技术,物理、化学和生物改性等方法对BC理化性质的影响。深入探讨了BC复合材料在CIP吸附领域的研究进展,包括影响因素、吸附机制以及当前研究的不足,并对未来BC吸附技术的发展方向进行了分析和展望。旨在为科研工作者提供一个全面而深入的视角,以促进该领域的知识积累和技术创新。
Efficient removal of antibiotics such as ciprofloxacin(CIP)—frequently detected in diverse environmental media—has become a critical research focus due to their potential risks to human health and ecosystems.Biochar(BC),a cost-effective and high-performance adsorbent,exhibits broad application potential in antibiotic removal owing to its low cost,excellent adsorption properties,and favorable regeneration capacity.However,the limited adsorption capacity of pristine BC for antibiotics hinders its practical application,necessitating further modification.This study summarizes the preparation techniques of BC and the effects of physical,chemical,and biological modifications on BC's physicochemical properties.Additionally,it discusses in depth the research progress of BC composites in CIP adsorption,including influencing factors,adsorption mechanisms,and limitations of current studies,while analyzing and prospecting future development directions of BC-based adsorption technology.This work aims to provide researchers with a comprehensive and in-depth perspective,thereby facilitating knowledge accumulation and technological innovation in this domain.
