dc.description.resumoThe textile industry uses large amounts of water in its processes. Such water ends up contaminated by a number of substances, including dyes, creating an environmental challenge. The present study aims at removing dye by applying the precipitation process using a sodium soap (anionic surfactant), derived fromanimalfat andvegetable oil,promotingdyedecontaminationusing biodegradablematerials. Sodium soap, in the presence of calcium ions, forms another insoluble surfactant. This new surfactant, under stir ring, aggregates and forms hydrophobic flocs that are capable of adsorbing organic materials dissolved in aqueous solutions, including dyes. Dye removal was assessed considering the influence of initial sur factant concentration, temperature, pH, presence of electrolyte, equilibrium time, and stirring rate. Dye removal efficiency reached 97.6%pt_BR
