| dc.description.abstract | There are several parameters influencing the sorption of analytes to soils. In this Master project, the sorption behavior of enrofloxacin (ENR) was characterized in six soils of basic pH and different properties, through the study of sorption isotherms. The Freundlich model fitted all the data, while the Langmuir equation was adjusted only to the soils showing an L-type isotherm. The values of experimental distribution coefficients (Kd) obtained for ENR ranged from 0.69 to 2.04 L/g, in agreement with the ones found in the literature. Principal component analysis was performed in the set of soils, and the properties that appeared to have a greater influence in ENR sorption were the content in Fe, Al and Mg oxides. In order to determine the role of organic matter (OM) in the ENR sorption process, one of the soil samples was amended with different amounts of humic acids. The values of Kd obtained seem to indicate an increase in sorption with the increase in OM. Further investigation is needed to confirm these findings. | pt_PT |
