Abstract
The present invention relates to a geopolymer produced from a synthetic aluminosilicate. The synthetic aluminosilicate was produced by sol gel technology, heat treated and, later, activated using sodium silicate and sodium hydroxide in solution, having as a final product a synthetic geopolymer. The final product was submitted to COadsorption analysis using thermogravimetry for adsorbed quantification. In addition to the pure geopolymer, it is also possible to produce the synthetic geopolymer with the addition of surfactant, or in the composite form with the addition of zeolite, or heat treated to form a zeolite or functionalized with amine, for example, to increase the adsorption capacity.
