Preparation,Characterization and Properties of Superparamagnetic Magnetic Resonance Contrast Agent
In this paper,superparamagnetic magnetic resonance contrast agent was synthesized by using FeCl3·6H2O as raw material,using ethylene glycol as solvent and polyvinyl pyrrolidone(PVP)as modification agent.Take it as the experimental research object.X-ray powder diffractometer and transmission electron microscope scanning electron microscope were used to study the morphology and size of the samples;the purity and chemical bond composition of the samples were investigated by using Fourier transform infrared spectroscopy(FTIR);and the crystallinity and magnetic properties of the samples were investigated by using magnetic measurement system(SQUID).
