The humic substances (HS) are macromolecular components resulting from chemical and biological degradation of vegetal and animal residues. It are widely distributed in soils, natural waters and sediments. Studies demonstrated that hydrotermic carbonization of biomass makes a carbon recalcitrant rich material, denomitated hydrotermal coal and a liquid fase denominated process water. The process uses mild temperatures of at most 300°C, humid biomass and self-generated pressure. The process water presents high quantities of organic matter and some nutrients. This project aims to characterize and study a complexant capacitie of "humic material", extracted from process water with metals copper and aluminium.This project the HTC will be made using the subproducts of sugarcane sector, the sugarcane bagasse and the vinasse. The carbonization will be realized in 232°C using a misture of sugarcane bagass and vinasse with addition of 1 and 4 percent of sulfuric acid. The humic material will be extracted following the recomendations of International Society of Humic Substances. The humic material extracted from process water will be characterized in elementar analysis (CHNS), concentration of total organical carbon (TOC) analysis, ultraviolet-visible spectroscopy, molecular fluorescence and nuclear magnetic resonance (NMR) (AU)
