چکیده
Abstract. A novel coating for solid-phase microextraction (SPME) fibers was manufactured by using a mixture of 1-decyl-3methylimidazolium tetrafluoroborate ionic liquid and commercial adhesive deposited on an etched stainless-steel support. The new characterized applying optical electron microscopy, infrared spectroscopy its extraction capacity also evaluated. tested as model analytes some pharmaceutical personal care products (PPCPs) with different hydrophilicities. potential use the fiber evaluated through direct-immersion mode extractions showed toward methylparaben, propylparaben, naproxen, diclofenac benzophenone-3. Experimental design tools were used to study optimize variables that affect desorption processes SPME direct immersion. analytical performance proposed method investigated under procedure´s optimal conditions, coupled high-performance chromatography-diode array detector (HPLC-DAD) method, which developed validated analysis target PPCPs. immersion linear, precise accurate. Detection quantification limits 0.023 0.093 μg mL-1 0.118 0.279 obtained, respectively. By tap water samples analyzed recoveries from 3.39 183.29 % found. presented adequate stability good reproducibility (<15 RSD). As final point, this device is easy quick preparation, inexpensive, suitable Resumen. Se fabricó un nuevo recubrimiento para fibras de microextracción en fase sólida utilizando una mezcla del líquido iónico tetrafluoroborato 1-decil-3metilimidazolio y adhesivo comercial depositada sobre soporte acero inoxidable grabado. El se caracterizó mediante la aplicación microscopía óptica electrónica, espectroscopía infrarrojo también evaluó su capacidad extracción. La extracción probó como analitos modelo algunos productos farmacéuticos cuidado con diferentes hidrofilicidades. uso potencial nueva fibra extracciones modo inmersión directa mostró hacia metilparabeno, propilparabeno, naproxeno, diclofenaco benzofenona-3. utilizaron herramientas diseño experimental estudiar optimizar las que afectan los procesos desorción por directa. rendimiento analítico método propuesto investigó condiciones óptimas procedimiento SPME, acoplado cromatografía líquida alto arreglo diodos (HPLC-DAD), fue desarrollado validado el análisis PPCPs objetivo. lineal, preciso exacto. obtuvieron límites detección cuantificación mL-1, respectivamente. Mediante desarrollado, analizaron muestras agua grifo encontraron recuperaciones %. presentó adecuada estabilidad buena reproducibilidad Como punto final, este dispositivo es fácil rápida preparación, económico adecuado
