Abstract
The present work aims to synthesize 70% cobalt / 30% multiwalled carbon nanotube (MWCNT) nanocomposites with enhanced physical properties. The structural, and magnetic properties of the Co1.5Fe1.5O4/MWCNTs are reported. Structural, morphological properties of the nano composites are characterized by XRD, HR-TEM, Raman, and XPS techniques. XRD and HR-TEM investigations support the development of a single-phase cubic spinel structure of Co1.5Fe1.5O4 confined on the exterior surfaces of MWCNTs. The measurements using a vibrating sample magnetometer (VSM) revealed ferrimagnetic nanocomposites. Heavy metal intrusion into the water system is a global environmental problem. Using Co1.5Fe1.5O4/MWCNT nanocomposites, the current study seeks to eliminate trace elements, including copper (Cu) and zinc (Zn). The main advantages of the synthesized samples include their high ad-sorption, amazing recycling efficiency, low cost, and simplicity of separation. Finally, one can conclude that the CNTs/Co1.5Fe1.5O4 are superior to other ad-sorbents in terms of effectiveness, sustainability, and environmental impact.
