The herbicide terbuthylazine (TBA) has displaced atrazine in most of EU countries, becoming one of the most regularly used pesticides and, therefore, frequently detected in natural waters. The affinity of TBA for soil organic matter suggests prolonged contamination; degradation leads to the release of the metabolite desethylterbuthylazine (DET), which has higher water solubility and binds more weakly to organic matter compared to the parent compound, resulting in higher associated risk for contamination of groundwater resources. Additionally, TBA and DET are chemicals of emerging concern because of their persistence and toxicity towards aquatic organisms; moreover, they are known to have significant endocrine disruption capacity to wildlife and humans. Conventional treatments applied during drinking water production do not lead to the complete removal of these chemicals; activated carbon provides the greatest efficiency, whereas ozonation can generate by-products with comparable oestrogenic activity to atrazine. Hydrogen peroxide alone is ineffective to degrade TBA, while UV/H₂O₂ advanced oxidation and photocatalysis are the most effective processes for oxidation of TBA. It has been determined that direct photolysis gives the highest degradation efficiency of all UV/H₂O₂ treatments, while most of the photocatalytic degradation is attributed to OH radicals, and TiO₂ solar-photocatalytic ozonation can lead to almost complete TBA removal in ∼30 min. Constructed wetlands provide a valuable buffer capacity, protecting downstream surface waters from contaminated runoff. TBA and DET occurrence are summarized and removal techniques are critically evaluated and compared, to provide the reader with a comprehensive guide to state-of-the-art TBA removal and potential future treatments.

除草剂叔丁嗪（TBA）已在大多数欧盟国家中取代了阿特拉津，成为最常用的农药之一，因此在天然水中经常被发现。TBA对土壤有机质的亲和力表明污染时间延长。降解导致代谢产物去乙基叔丁基噻嗪（DET）的释放，与母体化合物相比，其具有更高的水溶性，并且与有机物的结合更弱，从而导致地下水资源污染的相关风险更高。另外，TBA和DET由于对水生生物具有持久性和毒性而成为令人关注的化学品。此外，已知它们对野生生物和人类具有显着的内分泌破坏能力。饮用水生产过程中采用的常规处理方法不能完全清除这些化学物质；活性炭提供了最大的效率，而臭氧化可以产生副产物，其雌激素活性与阿特拉津相当。单独的过氧化氢不能有效降解TBA，而UV / H₂ O ₂先进的氧化和光催化作用是最有效的TBA氧化方法。已经确定，直接光解在所有UV / H ₂ O ₂处理中具有最高的降解效率，而大多数光催化降解归因于OH自由基，而TiO ₂太阳光催化臭氧化可导致〜几乎完全去除TBA。 30分钟。人工湿地提供了宝贵的缓冲能力，可以保护下游地表水免受污染的径流。总结了TBA和DET的发生，并对去除技术进行了严格的评估和比较，以为读者提供有关最新的TBA去除和潜在的未来治疗方法的全面指南。
