Abstract

In this study, a bimetallic nickel-doped Zn-MOF (Ni@Zn-MOF) was successfully fabricated by the hydrothermal method for the removal of norfloxacin (NOR) in pharmaceutical wastewater. The structural and surface characteristics of Ni@Zn-MOF were systematically characterized using SEM-EDS, BET, XRD, FT-IR, XPS, and Zeta potential analyses. The experimental results demonstrated that NOR could be effectively removed within a wide pH range from 3 to 11, achieving a maximum removal efficiency of approximately 94 % under optimal adsorption conditions. The adsorption behaviors of NOR were in good accordance with the pseudo-second-order kinetic model and the Freundlich isotherm model. The adsorption mechanism study revealed that the good adsorption performance originated from the synergistic effects of multiple interactions, including pore filling, metal coordination, electrostatic attraction, hydrogen bond, and π-π stacking interactions. Notably, the adsorption-saturated Ni@Zn-MOF demonstrated exceptional regeneration capability and stability, maintaining removal efficiencies above 60 % for NOR after five consecutive adsorption-desorption cycles. The current study suggests that the engineered Ni@Zn-MOF nanocomposite can be as a promising functional material for sustainable removal of residual antibiotic contaminants in practical wastewater treatment applications.

镍掺杂Zn-MOF对诺氟沙星抗生素的高效吸附：吸附行为及机理

本研究采用水热法制备了一种双金属镍掺杂Zn-MOF (Ni@Zn-MOF)，用于去除制药废水中的诺氟沙星（NOR）。利用SEM-EDS、BET、XRD、FT-IR、XPS和Zeta电位分析对Ni@Zn-MOF的结构和表面特征进行了系统表征。实验结果表明，在3 ~ 11的较宽pH范围内，NOR可以有效去除，在最佳吸附条件下，NOR的最大去除率约为94%。硝酸氮的吸附行为符合拟二级动力学模型和Freundlich等温线模型。吸附机理研究表明，良好的吸附性能源于孔隙填充、金属配位、静电吸引、氢键和π-π堆积等多种相互作用的协同作用。值得注意的是，吸附饱和Ni@Zn-MOF表现出卓越的再生能力和稳定性，在连续五次吸附-解吸循环后，对NOR的去除率保持在60%以上。目前的研究表明，工程Ni@Zn-MOF纳米复合材料可以作为一种有前途的功能材料，在实际的废水处理应用中可持续地去除残留的抗生素污染物。
