In this work it is proposed the usage of montmorillonile for zinc and copper ion removal from electrochemicai effluents. The initial concentrations of zinc etfluents analyzed in this work, varied between 1O and 94 ppm in Zn2+, being the pH between values 6-7. The obtained percentage of removal with calcic and sodic montmorillonite surpassed in all the cases 98%. The initial concenlrations of copper effluents oscillated between 16 and 160 ppm. in Cu2•. In the treatment of these effluents with calcic montmorillonite an elimination between 98.5 and 85.5% was reached al pH values between 4-5. In both cases it was used a relation of 5 grams ot clay 1200 milliliters of effluent for one hour agitation .

The present study has as main objecuve the search of new materials, among them the porous materials whose diversity of pore diameter confers lO the same specific properties, those that in turn determine a series of applications like adsorbents. catalysts, and shield materials, among others. The investigatíon consists of the synthes1s of macroporous materials by the method Sol-Gel, using reactive of low cost as sodium silicate (silicon source) and includes/understanos the following stages: 1) control of hydrolysis of the inorganic precursors: 2) formatíon oí the rnacrostructure material (hydrothermal synthesis) and 3) elimination of the organic matter by calcinations. The structural characterization and the degree of crystalinidad were made by means of Diffraction of Rays-X (DRX) and Electronic Diffraction of Area Selecta.(DEAS), whereas the morphologic analysis was made through an Ele...
