稀土元素在光催化降解抗生素中的应用研究进展

摘要：抗生素广泛应用于医疗和农业生产之中，由于传统的废水处理工艺不能够有效地去除废水中的抗生素，导致目前环 境中已经广泛检测到抗生素的存在。为了预防抗生素污染扩散带来的危害，人们投入了大量的资源研究抗生素的去除方法。本 文参考国内外文献总结了近几年稀土元素在光催化降解抗生素中的应用研究情况，深入揭示了稀土元素在光催化降解抗生素应 用中发挥的作用。主要内容包括：稀土元素掺杂、稀土元素参与构建异质结和稀土元素掺杂与异质结共用的光催化降解；稀土 元素应用在光催化降解抗生素中的3种方法的分析对比；对稀土元素应用于光催化降解抗生素的未来展望。

Application and research progress of rare earth elements in photocatalytic degradation of antibiotics

Abstract Antibiotics are widely used in medical and agricultural production. Since the traditional wastewater treatment technology can not effectively remove the antibiotics from wastewater, antibiotics have been widely detected in the environment. In order to prevent the ecological damage caused by the spread of antibiotic pollution, researchers began to invest many resources to study the removal methods of antibiotics. In this paper, we summarized the application and research progress of rare earth elements in photocatalytic degradation of antibiotics by reviewing the domestic and foreign literatures, and the role of rare earth elements in photocatalytic degradation of antibiotics was deeply revealed. The main contents include: the photocatalytic degradation by rare earth elements doped, the photocatalytic degradation with construction of heterojunction photocatalysts with rare-earth elements and the photocatalytic degradation with the two work together; analysis and comparison of three application methods of rare earth elements in photodegradation of antibiotics; prospect of the application of rare earth elements in photocatalytic degradation of
