Brazil has put on the international scene as the largest producer of orange juice in the world, most of this cultivation is found in the state of São Paulo. Consequently it has a huge amount of waste generated in terms of peel and pulp of the orange, thus causing a significant impact on the environment and are harmful to public health. Therefore this research project aims to quantify by thermogravimetric analysis the concentration of coke generated by the pyrolysis of orange peel. This pyrolyzed organic residue (coke) is also tested as an adsorbent for organic contaminants such as phenol. Samples are collected and dried at 110 °C. The technique used to determine the adsorption is a spectrophotometer (UV-Vis), and a description of the adsorption equilibrium will be used Freundlich and Langmuir models. This product may be applied for treating aqueous systems contaminated, to remove this contaminant.(AU)
