dc.description.abstract | HDL-MgFe is a Hydrotalcite that represent a compound lamellar double hydroxide. It was prepared through the continuous co-preparation method. The solid was characterized by surface area measurements, X-ray diffraction and temperature-programmed desorption of CO2. The adsorbent was used for the adsorption of Reactive Red 120 dye, and the factors affecting the adsorption were discussed, including concentration of adsorbent solid and contact time. The adsorption isotherms data were fitted to the Langmuir, Freundlich, Redlich-Peterson, Sips and BET models. The most suitable adsorption conditionswere found at a contact time of 60 min and solidconcentrarion of 2g.L -1 . The results for MgFe hydrotalcite showed a high adsorption with percentage about 90% of dye removal. Langmuir and Redlich-Peterson models were the isotherms that best described the removal process. | en |
