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.

基于噻二唑配体的漆酶样纳米酶，具有高 Cu+ 比例，可通过聚合有效去除四环素


一种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、低二氧化碳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有限。在这项研究中，我们受天然漆酶的启发，使用2-氨基-1,3,4-噻二唑作为配体合成了具有高Cu比例的漆酶模拟纳米酶（Cu-ATZ）。与天然漆酶相比，Cu-ATZ 对更恶劣的应用条件表现出更强的耐受性，并提高了稳定性，从而展示了更广泛的潜在应用。 Cu-ATZ 优异的催化性能使纳米酶能够用于聚合过程中去除水中的四环素。为了模拟实际的水体抗生素污染，在污水处理厂的水中添加了四环素。对水样进行 Cu-ATZ 处理后，发现化学需氧量 (COD) 含量降低了 80% 以上。总之，本研究提出了一种从水中消除四环素的新方法。
