Impacto del tratamiento con ozono sobre las propiedades superficiales del carbón activado

Abstract: RESUMENEl uso conjunto de ozono y carbón activado para tratar efluentes tóxicos ha sido demostrado recientemente. Sin embargo, existen dudas acerca del efecto del ozono sobre las propiedades del carbón activado. En este artículo se presentan resultados sobre la modificación de las propiedades superficiales de un carbón activado comercial por la acción del ozono durante diferentes tiempos de exposición. Las propiedades químicas superficiales del carbón activado fueron evaluadas utilizando las técnicas de neutra… Show more

“…Figure 8 shows the PZC results. When the pH of the solution is lower than the PZC, the total charge of the solid surface is positive, while if the pH of the solution is greater than the PZC, the surface is negatively charged [41,42]. The cryogel QEFe showed a less slightly acidic PZC compared to the cryogel QE (6.1 and 7.0, resp.…”
