Facile synthesis of magnetic high-efficiency renewable nanosorbent for recyclable adsorption of Cu2+
This study focuses on the synthesis and characterization of recyclable nano-adsorbents of magnetic nanocomposites (Fe3O4@ZnO-RGO). The Fe3O4 nanoparticles were used as magnetic responders, ZnO coated on the surface of Fe3O4 not only captured Cu2+ but also prevented the oxidation of Fe3O4, and reduced graphene oxide (RGO) acted as Fe3O4@ZnO carrying platform could effectively adsorb Cu2+. The physical and chemical performance characterization suggested that the nano-adsorbents had stable structure, good hydrophilicity, and magnetic properties. Furthermore, the research results on adsorption performance indicated that the Fe3O4@ZnO-RGO had high adsorption properties for Cu2+, and the adsorption rate could reach more than 98%. The adsorption process conformed to the Langmuir model and second-order adsorption kinetics, and the adsorption of Cu2+ was mainly chemisorption, accompanied by physical adsorption. In addition, because of the special magnetic response performance, Fe3O4@ZnO-RGO could be quickly separated from the solutions for cyclic adsorption so as to avoid secondary pollution. This provided a valuable idea for the effective development of clean and efficient Cu2+ adsorbents, and the Fe3O4@ZnO-RGO had great application potential in the field of Cu2+ wastewater treatment.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
