Ychwanegu Tag | Crynodeb: | The Ecuadorian coast has a diverse environment with unique geological formations in minerals that could be applied as added-value biomaterials. This research aims to investigate the magnetic properties and mineral composition of magnetic black sand samples from the coastal locations of Anconcito and Mompiche in Ecuador. The samples were characterized using a multitechnique approach, including vibrating sample magnetometry (VSM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and energy dispersive X-ray spectroscopy (EDX). The samples were coated with polymers such as Poly (aminoester) (PC), polyethylene glycol (PEG), chitosan, and polyvinylpyrrolidone (PVP). The study focuses on the effect of the mineral composition, the particle size, and the different polymer coatings on the magnetic properties. The results reveal significant variations in magnetic properties as a result of the coatings and mineral composition. This comprehensive analysis not only enhances the understanding of Ecuador’s coastal environments that could be used for potential applications in biomaterials, environmental remediation, and advanced ma-terial technologies. |
