摘要： 本文采用一种快速简便的策略在室温下合成了一种镓基金属有机凝胶（Ga-TATB）。Ga-TATB具有较大的比表面积、独特的分级多孔结构和优良的结构稳定性，能够有效去除水溶液中的四环素（TC）。吸附过程符合拟二级动力学模型和Freundlich等温线模型，在pH = 6.00、温度为25 ℃条件下的最大吸附量可达149.92 mg/g。此外，系统考察了溶液pH、计量比、离子强度、共存的无机离子、接触时间、初始TC浓度等因素对吸附过程的影响，并结合实验结果提出了Ga-TATB吸附四环素可能的机理。值得注意的是，较强的抗干扰能力和稳定的重复利用性，使得Ga-TATB在四环素类抗生素废水修复中具有很好的应用前景。

Abstract: In this research, Ga-based metal-organic gels (Ga-TATB) were synthesized at room temperature through a rapid and simple strategy. Ga-TATB could effectively remove tetracycline (TC) from aqueous solution due to the large specific surface area, unique porous structure and excellent structural stability. The adsorption process of TC by Ga-TATB kept well to the pseudo-second-order kinetic model and the Freundlich isotherm model, and the maximum adsorption capacity could reach 149.92 mg/g at pH = 6.00 and temperature of 25 ℃. Furthermore, the effect of solution pH, Ga-TATB dosage, ionic strength, coexisting inorganic ions, contact time and TC concentration on the adsorption process were systematically investigated, and the possible mechanism of Ga-TATB adsorption towards TC was proposed based on the experimental results. It is worth noting that the strong anti-interference ability and stable reusability make Ga-TATB a good application prospect in tetracycline antibiotic wastewater remediation.
