Study and Characterization of Super Paramagnetic Nanoparticles Coated with Chitosan Polymer (SPIONs-CS)

Preparation of iron salts Fe + 3 Fe+2 This study aims to prepare super-magnetic nanoparticles coated with chitosan-CS SPIONs in an easy and inexpensive chemical way, which is the method co-precipitation mediated aqueous solution mixing it a chitosan CS dissolved dilute citric acid 1 % precipitation this mixture NaOH sodium citrate as surfactant inside closed system using inert atmosphere for nitrogen gas N2 packaging during preparation. These particles were diagnosed by (XRD), was found that SPIONs-CS contain crystal structure oxide polymer shell did not affect its phase. It has super magnetic property decreases increasing concentrations encapsulating particles, but sufficient respond field. from diagnostic results prepared secondary within nanoscale 20 nm according TEM, Converging obtained size 22.8 XRD technique, Zeta potential analysis showed had negative surface charge after encapsulation zeta voltage -28.4mv at 0.125 concentration.g . (SEM) diagnosis are spherical shape spaced used average diameter (27.58nm, 20.023nm 35.127nm) three (0.100g, 0.125g, 0.150g), respectively.
