Modificación química de carbones activados y su efecto en la adsorción de compuestos fenólicos

Abstract: En este trabajo se impregnaron dos carbones activados comerciales, uno granular y otro pelletizado, con solucionesacuosas de ácido fosfórico (H3PO4), e hidróxido de potasio (KOH) en concentraciones de 60% p/p en condicionesde temperatura moderada (18°C). Se observó que la impregnación con ácido fosfórico produce un aumento en lacapacidad de adsorción de 2,4-dinitrofenol con respecto a los carbones de partida. La adsorción se determinó a partirde la elaboración de las isotermas desde solución acuosa de fenol y … Show more

“…There are several methods for removing phenolic compounds from water, which include polymerization, 5,6 photocatalytic degradation, 7,8 ozonation, 9,10 electrocoagulation, 11 extraction, 12,13 advanced oxidation, 14–16 ion exchange, 17–19 distillation, 20 biological treatment, 21 enzymatic treatment, 22–24 Electro‐Fenton method, 25,26 and adsorption 27–30 . Among them, adsorption is the most used due the simplicity of the process.…”

“…[1][2][3][4] There are several methods for removing phenolic compounds from water, which include polymerization, 5,6 photocatalytic degradation, 7,8 ozonation, 9,10 electrocoagulation, 11 extraction, 12,13 advanced oxidation, [14][15][16] ion exchange, [17][18][19] distillation, 20 biological treatment, 21 enzymatic treatment, [22][23][24] Electro-Fenton method, 25,26 and adsorption. [27][28][29][30] Among them, adsorption is the most used due the simplicity of the process. The adsorption efficiency will depend on the properties of the adsorbent material, such as porosity, reaction composition, size and surface area, pore size distribution, concentration of adsorbate, in addition to competition to other residues for the surface area of the adsorbent.…”
