El estudio de adsorción de los herbicidas y metabolitos por los suelos y GC se llevó a cabo mediante la técnica de &#8220;batch&#8221; en el equilibrio. Las concentraciones de equilibrio de los compuestos se determinaron por HPLC-MS, excepto las de 14C-iodosulfuron-metil sodio que fueron determinados en un contador de centelleo líquido. Las isotermas de adsorción se ajustaron a la ecuación de Freundlich, presentando una forma lineal para la adsorción de los herbicidas por el suelo B + GC. Los valores de Kf de aminopiralid fueron mayores que los de iodosulfuron-metil sodio, indicando una mayor adsorción de este herbicida por los suelos. La capacidad de adsorción de los herbicidas y sus metabolitos por los suelos enmendados dependió del contenido en carbono orgánico (CO) y del pH del suelo. Para todos los compuestos el porcentaje adsorbido por GC fue mayor que por los suelos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The objective of this work was to study the adsorption of aminopyralid and iodosulfuron-methyl sodium, applied in post-emergence to wheat crops, and two degradation products, metsulfuron-methyl and 2-amino-4-methoxy- 6-methyl-1,3,5-triazine (AMMT), by green compost (GC) and by two agricultural soils (soil A and soil B) with different characteristics, without amendment and amended with GC at 2.5% w/w. The study of herbicide and metabolite adsorption by soils and GC was carried out using the batch equilibrium method. The equilibrium concentrations of the compounds were determined by HPLC-MS, except for 14C-iodosulfuron-methyl sodium, which was determined in a liquid scintillation counter. The adsorption isotherms were fitted to the Freundlich equation, presenting a linear form for the adsorption of the herbicides by the soil B + GC. The Kf values &#8203;&#8203;of aminopyralid were higher than those of iodosulfuron-methyl sodium, indicating a greater adsorption of this herbicide by soils. The adsorption capacity of herbicides and their metabolites by amended soils depended on the soil organic carbon (OC) content and the pH. For all the compounds, the percentage adsorbed by GC was higher than by the soils.]]></p></abstract>
