Why is it important?
The synthetic iron oxide nanoparticles were characterized using FTIR, streaming current potential (SCP) and X-ray diffraction techniques. Particle size distribution of bare and coated nanoparticles was investigated by dynamic light scattering (DLS) technique and transmission electron microscopy (TEM).
Perspectives
The results obtained revealed that the CTAB modification effectively decreased the particle size and enhanced the dispersion of the particles in solution. In addition, simple separation by using a magnetic field was achieved because CTAB did not alter the superparamagnetic properties of particles.
