| contents | Treatment of acidic dyes solutions by adsorption in soybean meal Luana Marcele Chiarello Ivonete Oliveira Barcellos Gabriela Spengler Davi Eduardo Roza Ingeniería soybean meal acid textile dyes wastewater treatment In this study, we tested the potential use of a natural sorbent based on soybean meal from oil extraction in the treatment of solutions containing the acid dyes: yellow Erionyl RXL, navy blue Erionyl R and red Erionyl A-3B, used to dye polyamide fibers. To that end, adsorption studies were performed under different conditions of temperature, adsorbent concentrations, pH values, and color mixes (two- and three-color) on dye solutions produced in laboratory. Soybean meal showed great ability to remove color, especially in solutions with pH 4 and 6 at 60°C and containing 10 g L-1 of adsorbent. Considering that values of adsorption efficiency ranged between 74 and 99%, depending on the dye and treatment conditions, soybean meal proved to be an alternative material for the adsorption of acidic dyes. 2012 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303226534014 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
