Magnetic Porous Controlled Fe3O4-Chitosan Nanostructure: An Ecofriendly Adsorbent for Efficient Removal of Azo Dyes.

ABSTRACT: In this work, chitosan/magnetite nanoparticles (ChM) were quickly synthesized according to our previous report based on co-precipitation reaction under ultrasound (US) irradiation. Besides ChM was in-depth structurally characterized, showing a crystalline phase corresponding to magnetite and presenting a spheric morphology, a "nanorod"-type morphology was also obtained after increasing reaction time for eight minutes. Successfully, both morphologies presented a nanoscale range with an average particle size of approximately 5-30 nm, providing a superparamagnetic behavior with saturation magnetization ranging from 44 to 57 emu·g-1. As ChM nanocomposites have shown great versatility considering their properties, we proposed a comparative study using three different amine-based nanoparticles,
