In this study, new silica-coated magnetic nanoparticles modified with p-(4-methoxy phenyl)-N-(3-triethoxy silyl) phosphonamide dithioic acide were synthesized using a normal method. The structure of the newly obtained nanoparticles was characterized by Fourier Transform InfraRed (FT- IR) spectroscopy, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Vibrating Sample Magnetometry (VSM), and Thermogravimetric Analysis (TGA). The surface of the nanoparticles modified with p-(4-methoxy phenyl)-N-(3-triethoxy silyl) phosphonamide dithioic acide showed to be an effective adsorbent for the selective extraction of the ion of Ag (I) from aqueous mixed metal ions solution also containing Co(II), Cu(II), Ni(II) and Pb(II). Moreover, the silver ion desorption was most efficient inthiosulfate (S2O32-).
