Core-shell Fe₃O₄@zeolite NaA as an Adsorbent for Cu².

ABSTRACT: Here, using Fe₃O₄@SiO₂ as a precursor, a novel core-shell structure magnetic Cu²⁺ adsorbent (Fe₃O₄@zeolite NaA) was successfully prepared. Several methods, namely X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), Transmission electron microscope (TEM), Brunauer Emmett Teller (BET) and vibrating sample magnetometry (VSM) were used to characterize the adsorbent. A batch experiment was conducted to study the Cu²⁺ adsorption capacity of Fe₃O₄@zeolite NaA at different pH values, contact time, initial Cu²⁺ concentration and adsorbent does. It is found that the saturated adsorption capacity of Fe₃O₄@zeolite NaA on Cu²⁺ is 86.54 mg/g.
