Abstract Humic substances are macromolecules originating from the decomposition of plant and animal residues . It are present in soils , sediments and water bodies , and due to its chemical constitution have hydrophilic and hydrophobic properties . Concerns environments has increased interest in the search for new materials that solve the problems caused by the input of organic and inorganic pollutants in water sources . In environments , humic substances interact with metals and organic substances affecting in this way the transport and mobility of these . Thus, this project proposes the development of organic-inorganic hybrids involving the characteristics of humic substances and alkoxysilanes for the treatment of industrial and / or domestic wastewater . These hybrids are prepared by sol - gel process from three different alkoxysilanes and commercial humic acid . The main objective is to evaluate the use of hybrid matrices based on silane-alkoxides and humic substance as efficient and selective adsorption materials in metal species ( Ni , Cu , Cr ) and emerging contaminants ( linurol and bisphenol A) . | |
