Remoción de Cr3+ de agua residual industrial con zeolitas naturales

Abstract

En este estudio, se evaluó la capacidad de las zeolitas naturales tipo mordenita y erionita en su estado natural y en su estado homoiónico sódico para remover el Cr3+ de las aguas residuales de la industria del curtido de pieles mediante pruebas experimentales de laboratorio en reactores tipo batch y reactores en columna. Las aguas residuales que se estudiaron, fueron licores de una industria curtidora localizada en la Cd. De México. Simultáneamente con las zeolitas naturales, se realizaron pruebas de remoción de cromo en reactores tipo batch con los adsorbentes sintéticos carbón activado y zeolita tipo 4A, utilizados en su forma comercial, esto a fin de comparar la capacidad de las zeolitas naturales con respecto a la capacidad de los adsorbentes sintéticos para la remoción de Cr3+ del agua residual.

In this study the capacity of mordenite type zeolite and erionite type zeolite was evaluated, for both, natural and homoionic sodic state for removing Cr3+ from tannery wastewater, lab tests were made in intermittent reactor studies and in fixed bed reactor studies. The studied wastewater, were liquors from a México City ́s tannery. At the same time, with the natural zeolites, tests of chromium removal were made in batch reactors type with synthetic adsorbent the activated charcoal and zeolite 4 A type, used in their commercial form, this is in order to compare the capacity of the natural zeolites in relation with the capacity of adsorbent the synthetic ones for the removal of Cr3+ of the wastewater.
