Reutilización de un residuo agrícola como bioadsorbente para la eliminación de colorantes catiónicos de las aguas residuales de tintura

Abstract

Se ha comprobado la viabilidad de la cáscara de naranja químicamente modificada como medio de biosorción de colorantes catiónicos en las aguas residuales de la industria textil. De este modo, se ha utilizado y revalorizado un material que, en su mayor parte, se pierde como residuo de la industria agroalimentaria. El comportamiento como intercambiador catiónico fue comprobado con disoluciones sintéticas de Cu(ll). Finalmente, su capacidad como bioadsorbente fue evaluada con cuatro colorantes catiónicos, determinándose la influencia de diferentes parámetros como : concentración de bioadsorbente, tiempo de contacto, temperatura y pH del medio. lt has been verified the viability of the orange peel chemically. modified like a way of biosorption of cationic dyes in the waste water of the textile dyeing process. Therefore, it has been used and valued a material that is normally treated as a residue by. the food industry. Its behaviour as a cationic interchanger was verified with synthetic dissolutions of Cu (II). Finally, its capacity. as a biosorbent was evaluated with four cationic dyes, settling the influence of different parameters, taking into account the concentration of biosorbent, the time of contact, the temperature and the envoirment's pH
