Superparamagnetic iron oxide nanoparticles (SPIONs) have been widely used for their versatility, while it is coated with a biopolymer like chitosan that adds attraction and also increases its applications. In this study, SPION was synthesized by chemical co-precipitation method, characterized using various analytical techniques like UV-Vis, FTIR, SEM, EDX, TEM, AFM, XRD, zeta potential and Raman spectroscopy analysis. Chitosan was coated onto the SPIONs and used for water treatment to remove
