Abstract

A new magnetic nanoadsorbent was prepared by treating Fe3O4 nanoparticles with 3-aminopropyltriethoxysilane and 4-mercaptobenzoic acid was added to remove excessive mercury from aqueous solutions. 4-mercaptobenzoic acid was attached to Fe3O4 via the interaction between the carboxylic groups of 4-mercaptobenzoic acid and the amine groups of APTES. Fourier Transform Infrared Spectroscopy (FT-IR), elemental analysis, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Thermo gravimetric Analysis (TGA) were used to characterize the synthesized nanoparticles. The effect of pH, contact time, and some co-existing cations present in aqueous solutions, were investigated. Regeneration of adsorbed mercury could be possible up to 99.3 % by 1 M HCl and the modified MAGNETIC NANOPARTICLES can be re-used.
