Abstract
Surface of Fe3O4 nanoparticles (NPs) was coated with (3-mercaptopropyl)trimethoxysilane (MPTS) to form Fe3O4@MPTS NPs. Thus formed Fe3O4@MPTS NPs were studied for preconcentration of the representative Cd(II), Pb(II), and As(III) ions, and loading capacities toward these ions were found to be 17(±0.7), 29(±0.3), and 13(±0.5) mg g−1, respectively. As an example of safe utilization of toxic metal ions strongly bonded on magnetically retrievable NPs for catalytic applications, the Cd(II) loaded Fe3O4@MPTS NPs were successfully utilized for conducting the C−N bond formation reaction in comparable yields with that were reported in the literature but exhibited higher turnover number and turnover frequency.
