Magnetic Nanoparticles Functionalized with Carbamothioyl Benzamide as an Efficient Adsorbent to Remove Arsenic Ions from Aqueous Solutions

Magnetic nanoparticles (Fe3O4) were prepared through a simple reduction method. On the other hand, surfaceof magnetic nanoparticles was modified with N-((3-trimethoxysilyl) propyl) carbamothioyl benzamide, in which wassynthesized through the reaction between 3-aminopropyltriethyloxysilane (APTES) and benzoyl isothiocyanate(produced in situe, from the reaction between benzoyl chloride and potassium thiocyanate). Functionalized magneticnanoparticles were characterized by XRD, FT-IR, TGA, and SEM, and then were used as an adsorbent to remove arsenicfrom aqueous solutions.
