Abstract


In this article the synthesis of Fe3O4@MCM-41@NH-2,6-pydc as good adsorbent with potential of many applications, by coprecipitation method, was reported. For this purpose, Fe3O4 was synthesized, then protected with MCM-41 as a shell. Afterward, Fe3O4@MCM-41 functionalized by 2,6-pyridine dicarboxylic acid (pydc) after modifying by 3-aminopropyl trimethoxysilane (APTMS). This adsorbent characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray (EDX), scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET), differential thermal analysis (DTA), thermogravimetric analyses (TGA) and derivative thermogravimetric (DTG). The vibrating sample magnetometer (VSM) has been used to investigate its magnetic properties.
