Abstract
The problems of heavy metal and dye contamination in wastewater urgently requires green, efficient, and convenient removal strategy. In this paper, a new type of γ-Fe2O3/CeO2/cellulose nanofibril (CNF) composite film (CNFMONP film) adsorbent based on nanocellulose was facilely prepared which is green, easy to be recycled, and has high-efficiency adsorption performance. The proposed CNFMONP films exhibited rough surface, excellent mechanical properties, and stability performance, as well as satisfying adsorption removal performance for Pb2+ and Cu2+, with removal rates of 77.9% and 69.6%, respectively. In addition, a removal rate of up to 95.4% for the dye methylene blue (MB) was also achieved under UV illumination. The adsorption kinetics showed that the CNFMONP films were mainly chemisorbed for heavy metals. Besides, isotherm analysis indicated that monolayer adsorption is the adsorption behavior of the proposed film types adsorbent for heavy metals and dyes. Furthermore, the CNFMONP films still have excellent adsorption affinity after five rounds of cycles, with high adsorption efficiency of 75.0% for Pb2+ in complex environment. Therefore, environmentally friendly CNFMONP films with excellent stabilization and adsorption properties were simply prepared, which may provide a highly efficient way for recyclable and multi adsorption of heavy metals and dyes.
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.
