Preparation of ZnXFe3-XO4@chitosan Nanoparticles as an Adsorbent for Methyl Orange and Phenol

We have propounded an easy preparation process for the synthesis of chitosan-covered ZnXFe3-XO4 nanoparticles by the application of FeCl2.4H2O, FeCl3.6H2O, and Zinc Acetate. The synthesized nanoparticles, which went through various analysis methods, including transmission electron microscopy (TEM), scanning electron microscope (SEM), Energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), vibrating-sample magnetometer (VSM), and Fourier transform infrared (FT-IR) spectroscopy, were later on exploited as adsorbent for phenol and Mo contaminations. Trapped within a matrix of chitosan, the synthesized ZnXFe3-XO4 nanoparticles had a size of less than 30nm. The EDS and FTIR analysis methods demonstrated the presence of Zn element inside the structure and the NH2 group on nanoparticles’ surface, respectively. The coated nanoparticles had a magnetic saturation of 55 emu/g. Accordingly, the results showed that the synthesized nanoparticles had a very high capacity phenol and methyl adsorption.
