| Abstract (English): | Carbaryl is a widely used insecticide in the agricultural industry worldwide. Accumulation of this compound in the environment poses serious risks to both human health and ecosystems, particularly by impacting essential pollinators such as bees. The adsorption of carbaryl onto layered double hydroxides (LDH) has not been previously studied. In this work, a surfactant-modified LDH was synthesized via the coprecipitation method and evaluated as an adsorbent for carbaryl removal from water. The material, denoted as CaAl-PS-HDL, contains Ca and Al in the main layers, with sodium palmitate (PS) as the interlayer anion. This combination of cations and a natural, food-grade surfactant minimizes toxicity risks associated with the adsorbent. The aim of this work was to characterize the material using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FT-IR). As well as to evaluate its adsorption capacity for carbaryl and the effects of contact time, initial pesticide concentration, adsorbent dose, pH, and temperature on the adsorption process. A significant increase in the LDH basal spacing was observed after modification with PS. The adsorption capacity of CaAl-PS-LDH was significantly higher than that of the unmodified inorganic LDH, involving both hydrophobic and polar interactions between the contaminant and the adsorbent. Comparison with other clay- and mineral-type adsorbents indicates that CaAl-PS-LDH is suitable for potential application in the treatment of pesticide-contaminated water. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Carbaril es un insecticida ampliamente utilizado en la agricultura mundial. Su acumulación en el ambiente representa serios r iesgos tanto para la salud humana como para los ecosistemas, afectando particularmente a polinizadores esenciales como las abejas. E n este trabajo, se sintetizó un hidróxido doble laminar (HDL) modificado con un tensioactivo natural mediante el método de coprecipitación, y se evaluó su desempeño en la adsorción de carbaril del agua. El material, denominado CaAl-PS-HDL, contiene calcio y aluminio en sus capas principales, así como palmitato de sodio (PS) intercalado en el espacio interlaminar. Esta combinación de cationes y PS minimiza los riesgos de toxicidad asociados con el adsorbente. El objetivo del trabajo fue caracterizar el material mediante las técnicas de difracción de rayos X (XRD), microscopía electrónica de barrido con emisión de campo (FESEM), espectroscopía de dispersión de energía (EDS) y espectroscopía infrarroja por transformada de Fourier (FT-IR). Así como, evaluar la capacidad del material para adsorber el carbaril y los efectos del tiempo de contacto, la concentración inic ial del plaguicida, la dosis del adsorbente, el pH y la temperatura en el proceso de adsorción. Se observó un aumento significativo del espaciamiento basal del HDL tras la modificación con PS. La capacidad de adsorción de CaAl-PS-HDL fue significativamente mayor que la del HDL inorgánico, involucrando interacciones hidrofóbicas y polares entre el contaminante y el adsorbente. La comparación con otros adsorbentes de tipo arcilloso y mineral indica que CaAl-PS-HDL es adecuado para su potencial aplicación en el tratamiento de aguas contaminadas por pesticidas.
