dc.description.abstractSilica gel surface has been modified in two reaction steps: (i) the silylating agent 3-mercaptopropyltrimetox silane was firstly immobilized to give a surface Sil-SH and (ii) this precursor incorporated an ethylene Sulfide molecule to obtain the surface denoted Sil-SSH. This material was characterized by elemental analysis. IR spectroscope. thermogravimetry, solid state and C-13 and Si-29 NMR, and surface area measurement. These materials were employed as adsorbents for divalent heavy cations from aqueous Solutions at room temperature and the isotherms were adjusted to a modified Langmuir equation. The maxima number of moles adsorbed were 1.0, 1.5, 1.6, 2.2, 2.4 and 3.1 mmol g(-1) for Co, Cu, Ni, Cd, Pb. and Hg, respectively.pt
