A promising water treatment technology involves inducing the polymerization of organic pollutants to form corresponding polymers, enabling rapid, efficient, and low CO emission removal of these pollutants. However, there is currently limited research on utilizing polymerization treatment technology for removing tetracyclines from water. In this study, we synthesized a laccase-mimic nanozyme (Cu-ATZ) with a high Cu ratio using 2-amino-1,3,4-thiadiazole as a ligand inspired by natural laccase. The Cu-ATZ exhibited enhanced resistance to more severe application conditions and improved stability compared to natural laccase, thereby demonstrating a broader range of potential applications. The excellent catalytic properties of Cu-ATZ enabled the nanozyme to be used in the polymerization process to remove tetracyclines from water. In order to simulate actual antibiotic pollution of water bodies, tetracyclines were added to the water from sewage treatment plants. Following Cu-ATZ treatment of the water sample, the chemical oxygen demand (COD) content was found to have decreased by over 80 %. In conclusion, this study presented a novel approach for tetracycline elimination from water.
一种很有前途的水处理技术涉及诱导有机污染物聚合形成相应的聚合物，从而能够快速、高效、低 CO 排放地去除这些污染物。然而，目前利用聚合处理技术去除水中四环素的研究还很有限。在这项研究中，我们使用 2-氨基-1,3,4-噻二唑作为配体，模拟天然漆酶合成了一种高铜比的漆酶模拟纳米酶（Cu-ATZ）。与天然漆酶相比，Cu-ATZ 表现出更强的耐苛刻应用条件和更高的稳定性，因此具有更广泛的潜在应用。Cu-ATZ 的优异催化性能使其能够在聚合过程中用于从水中去除四环素。为了模拟水体中实际的抗生素污染，我们将四环素添加到污水处理厂的水中。水样经 Cu-ATZ 处理后，化学需氧量（COD）含量下降了 80%以上。总之，本研究提出了一种从水中去除四环素的新方法。
