dc.descriptionEichhornia crassipes is a plant considered a pest for the different aquatic ecosystems in the world. Furthermore, Cr (VI) is a highly toxic aquatic pollutant. The adsorption capacity of Eichhornia crassipes as a bioadsorbent was studied for the removal of Cr (VI) in a simulated wastewater. The ion concentration in solution, pH and temperature were studied using a symmetric factorial experimental design and applicating an ANOVA analysis. The highest Cr (VI) adsorption capacity (2.5 mgꞏg-1) was obtained at 75 ppm of Cr (VI), pH of 1.5 and 45 ° C. Surface functional groups were observed that, through electrostatic attraction and formation of hydrogen bonds, favored the adsorption of Cr (VI). This allows to conclude that this bioadsorbent is effective for the elimination of Cr (VI) in solution using a simple and low-cost process.en-US
dc.descriptionEichhornia crassipes es una planta considerada una plaga para los diferentes ecosistemas acuáticos en el mundo. Además el Cr (VI) es un contaminante acuático altamente tóxico. Se estudió la capacidad de adsorción de la Eichhornia crassipes como bioadsorbente para la remoción de Cr (VI) presente en un agua residual simulada. La concentración del ion en solución, pH y temperatura fueron estudiadas como variables en un diseño experimental factorial simétrico, y mediante análisis ANOVA. La mayor capacidad de adsorción Cr (VI) (2.5 mgꞏg-1) se obtuvo a 75 ppm de Cr (VI), pH de 1.5 y 45 °C. Se observaron grupos funcionales superficiales que mediante atracción electrostática y formación de puentes de hidrógeno favorecieron la adsorción de Cr (VI). Esto permite concluir que el bioadsorbente es efectivo para la remoción de Cr (VI) en solución con un proceso simple y de bajo costo. Eichhornia crassipes commonly called water hyacinth, is a plant considered a pest for the different aquatic ecosystems in the world. Furthermore, Cr (VI) is a highly toxic aquatic pollutant. In order to contribute to the solution of these two environmental problems, the adsorption capacity of water hyacinth as a bioadsorbent was studied for the removal of Cr (VI) in a simulated wastewater. The ion concentration in solution, pH y temperature were studied using a symmetric factorial experimental design y applicating an ANOVA analysis. The highest Cr (VI) adsorption capacity (2.5 mgꞏg-1) was obtained at 75 ppm of Cr (VI), pH of 1.5 y 45 ° C. Surface functional groups were observed that, through electrostatic attraction y formation of hydrogen bonds, favored the adsorption of Cr (VI).
