Resumen
[ES]En este estudio se plantea la utilización del residuo de poda de olivar como bioadsorbente de hierro (III) presente en disoluciones acuosas, como potencial vía de aprovechamiento de este material lignocelulósico. Este residuo agroindustrial, muy abundante en Andalucía especialmente en nuestra provincia (Jaén), tiene un coste reducido y una alta disponibilidad anual; este hecho, unido a los problemas medioambientales que ocasiona su quema incontrolada (contaminación del aire) o su depósito de manera masiva en el suelo hace que su valorización llegue a ser una prioridad. En esta memoria se estudia, además de la estabilidad de diferentes disoluciones de Fe (III), la capacidad adsorbente tanto del residuo de poda de olivar original como de éste sometido a diferentes pretratamientos así como el grado de eliminación de hierro por parte de algunos materiales celulósicos adicionales.
[EN]This study raises the possibility of using olive-tree pruning residue as bio-adsorbent of iron (III) aqueous solutions, considered as potential utilization strategy of this lignocellulosic material. This agro-industrial residue, quite abundant in Andalusia mainly in our province (Jaén), has a reduced cost and high annual availability; this fact, combined with traditional environmental problems derived from uncontrolled burning (air pollution) or its disposal at a massive scale on the ground, makes its valorization becomes a priority, currently. It has been studied, in this working memory, apart from stability of different iron (III) solutions, both adsorbent capacity of olive-tree pruning biomass together with the same material submitted to several pretreatments as well as the removal rate of iron of some additional cellulosic materials.
