Abstract

The stable water-based magnetic fluid was prepared by surface modification of Fe₃O₄ magnetic nanoparticles with sodium tripolyphosphate (STPP). The magnetic fluid was characterized by FTIR, TG, TEM, XRD, XPS, VSM and zeta potential. The results show that Fe₃O₄ magnetic nanoparticles are coated by STPP in surface. Particle surface acquires a negative charge at pH value above 3. It is found that STPP/Fe₃O₄ magnetic nanoparticles are superparamagnetic with a specific saturation magnetization of 62.3 A·m²·kg^-1.
