Abstract
Magnetic chitosan has excellent adsorption performance toward crude oil. It is suitable for large-scale adsorption and adsorbent can be separated from the medium by a simple magnetic process. In this paper, magnetic Ni0.5Mn0.5Fe2O4-chitosan nanoparticles were obtained using Ni0.5Mn0.5Fe2O4 as cores and chitosan as a polymeric shell. The size, structure, and magnetic properties of the resultant magnetic nanoparticles were characterized by TEM, SEM, XRDm and vibrating sample magnetometer. The performance of surface activity was measured by TX-500C full-scale automatic dynamic spinning drop interfacial tension instrument.
