Abstract

Tetracycline contaminants are frequently found in groundwater and surface water, which contribute to the proliferation of antibiotic resistance genes, leading to significant environmental pollution. Adsorption technology is an efficient and reproducible remediation method. In this work, a bamboo-based composite biochar was prepared by attaching zeolitic imidazole framework-67 to delignified bamboo flakes, followed by carbonization using the solvothermal method to remove oxytetracycline hydrochloride from water. The chemical and physical properties of the composite were characterized using different surface analysis techniques. The findings revealed that zeolitic imidazole framework-67 modified bamboo-based composite biochar, with a maximum adsorption capacity of 310.74 mg·g⁻¹, adhered to the pseudo-second kinetic model and Langmuir isothermal model during the adsorption of oxytetracycline hydrochloride. The adsorption process was spontaneous, exothermic, and involved monolayer chemisorption. Possible mechanisms included electrostatic interactions, hydrogen bonding, physisorption and π-π interactions. This study demonstrates that the bamboo-based composite biochar possesses excellent adsorption properties for oxytetracycline hydrochloride and could serve as a cost-effective and environmentally friendly adsorbent for removing antibiotics from water.

竹基复合生物炭高效脱除盐酸土霉素

地下水和地表水中经常发现四环素类污染物，这有助于抗生素耐药基因的增殖，导致严重的环境污染。吸附法是一种高效、可重复的修复方法。以沸石咪唑骨架-67为载体，将沸石咪唑骨架-67吸附在去木质素竹片上，采用溶剂热法碳化脱除水中的盐酸土霉素，制备了竹基复合生物炭。采用不同的表面分析技术对复合材料的化学和物理性能进行了表征。结果表明，沸石型咪唑框架-67改性竹基复合生物炭在吸附盐酸土霉素过程中符合拟秒动力学模型和Langmuir等温模型，最大吸附量为310.74 mg·g−1。吸附过程为自发、放热、单层化学吸附。可能的机制包括静电相互作用、氢键、物理吸附和π-π相互作用。本研究表明，竹基复合生物炭对盐酸土霉素具有良好的吸附性能，可作为一种经济、环保的水中抗生素去除吸附剂。图形抽象

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
