Abstract

The waste from industries producing orange juice comes to meet 25,000ton/day causing a significant impact on the environment and is harmful to public health. Brazil is now the largest producer of orange juice in the world and most of this cultivation is found in the state of São Paulo. The aim of this project is a study the sorption of toluene, highly toxic organic contaminants found in water and soil, orange peel, dried at 110°C, and pyrolysis at various temperatures. The methodology used for sorption studies will be spectrophotometry in the UV-Visible region. The following will apply for validation and observation of the amount sorbed, and isotherms, applying the Langmuir and Freundlich models.(AU)
