Abstract: Among the toxic metals, mercury (Hg) is a highly toxic element, and hence, a suitable technology is required to remove it. An imprinted polymer exhibiting a high sensitivity for mercury (II) in aqueous solution is presented. Polymer particles imprinted with mercury (II) were synthesized by polymerizing aminothiophenol. The imprinted polymer was characterized by Fourier transform infrared spectroscopy, UV-vis spectroscopy, X-ray diffraction analysis, and scanning electron microscopy. Relative selective coefficients (k') of the imprinted polymer evaluated from selective binding studies between Hg2+ and Cu2+ or Hg2+ and Cd2+ were 64 and 27, respectively. These values indicated highly favored Hg2+ extractions over the two competing ions. The polymer has high analytical potential for selective extraction and pre-concentration of mercury (II) ions in the presence of closely related ions. Here we report simple synthesis of polymer with high selectivity and fast adsorption capability of Hg (II) ion over similar charge cations such as Cd (II) and Cu (II). The study shows that the polymer has a potential intern of reusability and high stability
