Performance and mechanism of a novel bamboo-based magnetic biochar composite for efficient removal of norfloxacin
Quinolone antibiotics have become prominent organic contaminants in aquatic ecosystems, significantly threatening the environment and human health. Efficient removal of these pollutants in an eco-friendly manner still remains a challenge. In this study, a simple and environmentally friendly bamboo-based magnetic biochar was prepared by KOH-activated magnetized hydrothermal method to remove the antibiotics norfloxacin (NOR) from water. The characterization results demonstrated that the KOH activation significantly increased the specific surface area of bamboo biochar, with KMDBC reaching 1253.66 m2·g−1. The adsorption process of NOR by KMDBC followed the Pseudo-second order kinetic model and Langmuir isothermal model, with a maximum adsorption capacity of 458.43 mg·L−1. Based on the thermodynamic results, the adsorption process was exothermic, spontaneous, and involved chemisorption, likely through π-π interactions, hydrogen bonding, and electrostatic repulsion. This study demonstrates that KMDBC is an effective and recyclable material for NOR removal, offering valuable insights into utilizing forest resources for environmental remediation.
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.
