An excessive utilization of tetracycline antibiotics (TCs) in aquaculture and livestock farming significantly threatens human health and the vitality of aquatic environments. In this work, we used a one-pot hydrothermal approach with APT@MIL53- hybrid material to achieve the selective removal of TC and OTC from agricultural wastewater. APT@MIL53- showed significant chemical stability in the 3-10 pH range. Analysis of the adsorption results using adsorption kinetics, adsorption isotherm studies and adsorption thermodynamics indicated the presence of a monolayer physicochemical adsorption process with a maximum equilibrium adsorption of 600.43 mg g for TC (removal efficiency of 93.5%) and 537.71 mg g for OTC (removal efficiency of 91.4%). The elimination of TCs was not significantly impacted by the common buffer system of solution or the presence of water. Furthermore, a number of characterization techniques, including FT-IR and XPS, suggested that electrostatic interactions, π-π stacking, and hydrogen were potential adsorption processes. APT@MIL53- showed stable recycling performance, maintaining a stable adsorption amount and chemical stability after six adsorption-desorption cycles of use, which proved that APT@MIL53- has application possibilities for the agricultural wastewater treatment process. This study illustrates that APT@MIL53(Fe)- hybrid material offers a novel method for the selective and effective elimination of agricultural wastewater.
在水产养殖和畜牧业中过度使用四环素类抗生素（TCs）对人类健康和水生环境的活力构成了重大威胁。在这项工作中，我们采用一锅水热法合成APT@MIL53-杂化材料，以实现从农业废水中选择性去除TC和OTC。APT@MIL53-在pH值为3至10的范围内表现出显著的化学稳定性。通过吸附动力学、吸附等温线研究和吸附热力学对吸附结果进行分析，结果表明存在单层物理化学吸附过程，对TC的最大平衡吸附量为600.43 mg/g（去除效率为93.5%），对OTC的最大平衡吸附量为537.71 mg/g（去除效率为91.4%）。溶液的常见缓冲体系或水的存在对TCs的去除没有显著影响。此外，包括傅里叶变换红外光谱（FT-IR）和X射线光电子能谱（XPS）在内的多种表征技术表明，静电相互作用、π-π堆积和氢键是潜在的吸附过程。APT@MIL53-表现出稳定的循环性能，在经过六次吸附-解吸循环使用后，保持稳定的吸附量和化学稳定性，这证明APT@MIL53-在农业废水处理过程中具有应用潜力。本研究表明，APT@MIL53(Fe)-杂化材料为选择性和有效去除农业废水提供了一种新方法。
