Composite magnetic microspheres: Preparation and characterization

In this study, composite magnetic microspheres have been synthesized based on artemisia seed gum and chitosan using the suspension cross-linking technique for use in the application of magnetic carrier technology. The properties of the composite magnetic microsperes, such as morphological, magnetic properties, thermal stability and the functional groups of the microspheres, were characterized by different techniques (i.e. SEM, magnetometry, DSC and FT-IR). The swelling kinetics and pH responsive behaviors of the composite magnetic microspheres were also studied.
