Atrazine is one of the most widely herbicides used in the world, being found in surface water and groundwater. It belongs to the s-triazines class classified as possible carcinogenic potential and toxicity presents as an endocrine disruptor. The acknowledged limitation of the water treatment processes, which employ chemical coagulation in atrazine removal and the risks to health, has motivated this work taking into regards the adsorption of activated carbon as an alternative technology. The experimental study consisted of physical characterization of activated carbon and of adsorption tests in waters of different organic content. It was possible to verify the capacity of activated carbon to remove atrazine, and the adsorption mechanism was influenced by the quality variation of water matrices generating isotherms with different characteristics.
