| description |
The present paper shows very high potential for two types of solid (a commercial alumina and material obtained by composting, i.e. matured compost) on Cr(VI) adsorption/elimination in aqueous solution using a concentration range close to those previously detected in waste-water from Colombian industries. Both had important properties for eliminating Cr(VI), the compost being more important as it represents low-cost material. Optimal conditions for chromium adsorption on alumina and compost were established. Initial Cr(VI) alumina concentration was 10 mgL-1, with 100 mL/g volume of solution per adsorbent mass, pH=2.0, 1 hour equilibrium time and 150 rpm stirring. For compost, initial Cr(VI) concentration was = 3 mg L-1, 50 mL/g volume of solution per adsorbent mass, pH=2.5, 3 hour equilibrium time and 150 rpm stirring. The experiments showed that compost adsorption properties could be enhanced by adding small quantities of alumina. Compost could thus be chosen as a promising material for use in bioremediation chromium-containing waste water in a management programme for using solid waste in for minimising environmental impact. |

Ambos materiales mostraron propiedades importantes para la eliminación de Cr(VI), considerándose de mayor relevancia el compost por ser un material de bajo costo. Se establecieron las condiciones óptimas para la adsorción de cromo sobre alúmina y sobre compost. Para la alúmina: concentración inicial de Cr(VI) = 10 mgL-1, volumen de solución por masa de adsorbente = 100 mL/g, pH = 2,0, tiempo de equilibrio = 1 hora, y agitación = 150 rpm. Para el compost: concentración inicial de Cr(VI) = 3 mg L-1, volumen de solución por masa de adsorbente = 50 mL/g, pH = 2.5, tiempo de equilibrio = 3 horas, y agitación = 150 rpm. Además, los resultados mostraron que las propiedades de adsorción del compost se pueden mejorar mediante la adición de pequeñas cantidades de alúmina. El estudio permitió seleccionar al compost como un material promisorio para procedimientos de remediación de aguas residuales que contienen cromo (VI) dentro de una política de manejo y uso de residuos sólidos con el objeto de minimizar el impacto ambiental de éstos.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/20537Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 31, núm. 1 (2011); 154-162 Ingeniería e Investigación; Vol. 31, núm. 1 (2011); 154-162 2248-8723 0120-5609Vargas-Niño, Claudia and Carriazo, José Gregorio and Castillo Serna, Elianna (2011) A study of low-cost adsorbent materials for removing cr(vi) from aqueous waste effluent.
