dc.description.abstract Aqueous effluents loaded with dye from various industries are major sources of pollution continues to water. Congo red is an azo dye anion. This class of dye is the most widely used in industry as well as dyes Azo are toxic, mutagenic, carcinogenic and cause major risk to aquatic life. The aim of our work is to eliminate the adsorption of Congo Red medium obtained from a food waste (spent grain), where the main criterion for choosing the latter is mainly based on purely economic considerations. The experimental results showed that the use of grains for the elimination of Congo red can reach a binding capacity of about 43.29 mg / g, in the rough and 117.65 mg / g after activation with sulfuric acid (40%).The modeling results showed good correlation of experimental data with the Langmuir model and less for the model of Freundlich . Activated carbons prepared from the grains can be recovered so they can be used in stations wastewater treatment. en_US
