Pinedo-Hernández, S. | Díaz-Nava, C. | Solache-Ríos, M.
The adsorption of Brilliant Blue FCF from aqueous solution was evaluated using a Fe-zeolitic tuff. The adsorbent was characterized by scanning electron microscopy, IR spectroscopy and X-ray diffraction. Sorption kinetic, isotherms, dose and pH effects were determined and the adsorption behavior was analyzed. Kinetic pseudo-first order and linear isotherm models were successfully applied to the experimental results, indicating that the sorption mechanism is physisorption. Experiments in columns were performed and breakpoint was found in 100Â min using a concentration of 5Â mg/l.
