摘要

X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Vibrating Sample Magnetometer (VSM), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM), were all used for purposes of the exploration of different characteristics on the part of the synthesized nanocomposite. Magnetic nanoparticles with chitosan are thought to be very efficacious absorbers to metal ions. It was for this reason that our research was set on producing them through a quick (and, the same time, simple) procedure. To prepare such a novel compound as CoFe2O4@SiO2@Chitosan, the application was made of CoFe(2)O(4)magnetic nanoparticles' co-precipitation property. Our method was capable of producing the novel CoFe2O4@SiO2@Chitosan most successfully so much so that CoFe(2)O(4)nanoparticles were properly anchored onto chitosan itself. It was also part of our methodology to take advantage of CoFe2O4@SiO2@Chitosan nanoparticles as sorbents to remove Cd (II) ions from the related aqueous solutions. Our best effort was made to enhance differing factors' effects employing bringing about optimal conditions. These factors comprised of pH adsorbent type, contact ultrasonication times, and acid concentration. The detection limit was finally arrived at by the level of 1.55 ng L-1. The cadmium linear range fell in between 0.007 and 0.500 ng mL(-1). The statistical SD for all of the eight replicates turned out to be +/- 2.7 0.50 ng mL(-1) of Cd (II): this was, of course, based on the approach inside the present article.
