dc.description.abstract | En el presente estudio se investigó un adsorbente aglomerado esferoidal de γ-Al2O3 obtenido a partir de pseudoboehmita para la eliminación eficaz de fluoruro de un medio acuoso. Las propiedades superficiales se caracterizaron por diversas técnicas: XRD, fisisorción de N2, FE-SEM/EDS, RMN 27Al, adsorción de piridina por FT-IR, PZy tamaño de partícula. Se llevaron a cabo experimentos en lotes y se compararon con una alúmina activada comercial (AA). El proceso se llevó a cabo a pH 5, 7 y 9, a 25 y 35 ºC. Los resultados experimentales indicaron que los aglomerados esferoidales de γ-Al2O3 eliminan hasta 15 mg/g, con una capacidad de adsorción mayor que AA de 13 mg/g, a pH 5, estudiados a 25 y 35 ºC. El proceso de adsorción de F-en γ-Al2O3 y AA siguió la cinética de pseudo-primer orden y la isoterma de Langmuir. Los resultados muestran un adsorbente eficaz para la eliminación de F-. | es_MX |

dc.description.abstractEnglish | A spheroidal agglomerate γ-Al2O3 adsorbent obtained from pseudoboehmite for effective removal of fluoride from aqueous medium was investigated in the present study. The surface properties were characterized by several techniques: XRD, physisorption of N2, FE-SEM/EDS, 27Al NMR, FT-IR Pyridine adsorption, PZ and particle size. Batch experiments were conducted and they were compared with a commercial activated alumina (AA). The process was carried out at pH 5, 7, and 9, then at 25 and 35 ºC. Batch experimental results indicated that the spheroidal agglomerates of γ-Al2O3 remove up to 15 mg/g with a higher adsorption capacity than AA of 13 mg/g, at pH 5, studied at 25 and 35 °C. The F−adsorption processes in γ-Al2O3 and AA followed the pseudo-first-order kinetics and the Langmuir isotherm. The results showed an adsorbent effective for removal of F−. | en |
