Abstract

A novel, reusable biomass-derived adsorbent biochar material, referred to as WS, was developed by pyrolyzing ball-milled walnut shell powder under an inert gas atmosphere, followed by chemical activation with sodium hydroxide (NaOH). The resulting biochar WS demonstrated rapid adsorption capabilities for trinitrotoluene (TNT) from wastewater, achieving equilibrium within 30 min. The maximum adsorption capacity was determined to be 107.0 mg·g⁻¹. Adsorption data were well-described by the Langmuir isotherm model and the pseudo-second-order kinetic model, indicating favorable adsorption characteristics. The efficient removal of TNT by WS was attributed to a synergistic mechanism involving electrostatic attraction and chemisorption.

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.
