Synthesis and Characterization of Magnetic Nanoparticles Coated Porous Material SBA-15 Functionalized with Amine Groups for the Separation of Cr4+and Fe3+ from Wastewater

Nowadays, the separation of heavy metals from industrial wastewater is one of the most important issue to protect the environment. The core-shell structure of Fe3O4 @ SBA-15 is a proper solid base for functionalization and separation of mixture reaction. The SBA-15 nanoparticles have a very high surface area that can be functionalization with the huge amount of organic groups. In this project, magnetic nanoparticles were synthesized with the co-precipitation method then coated with high-ordered surface area SBA-15 then functionalized with the organic ligand. The surface of these materials functionalized with 3-(2-aminoethylamino)-propyl amine. In order to the characterization of nanocomposite properties, some techniques such as IR, TGA, SEM, XRD, and BET analyzes were used. After synthesizing and characterization of Fe3O4@SBA-15@(CH2)3- NH-(CH2)2-NH2, this compound was used for the separation of heavy metals from in vitro manipulation matrix. The advantages of these materials can be noted such as high surface area, magnetic properties, and recoverable and non-toxic properties.
