Abstract

In this research a study of the adsorption of acetic, benzoic, butanoic, fumaric, maleic and succinic acids on sugarcane baggase ash is made. The adsorber material is characterized through physical criteria such as apparent and pictometric density, compressibility, porosity, superficial area and tortuosity. The sample has been examined by X-rays Diffraction, thermal analysis, IR-quality analysis. The isotherm for the sorption process is determined, where it is shown that the Freundlich model is adjusted to benzoic acid, the Langmuir and Toth model to acetic acid, Bunauer- Emmett- Teller (BET) model to succinic acid and the butiric, maleic and fumaric acids are adjusted to Langmoir model. It is established that the first-order model is adjusted to the adsorption kinetics of the acetic and benzoic acids; while the rest of the acids are adjusted to a second-order model, in the case of the butanoic, succinic and maleic acids it is possible the occurrence of chemisorption processes.
