En la Tesis Doctoral titulada "Sistemas de Extracción mediante electromembrana (EME) para la determinación de antiinflamatorios no esteroideos (AINEs) en orina humana", se plantea el desarrollo y empleo de diferentes sistemas de extracción mediante electromembrana (EME) para la puesta a punto y optimización de métodos de extracción que permitan...

Liquid phase microextraction (LPME) and electromembrane microextraction (EME) can be considered as two of the most popular techniques in sample treatment today. Both techniques can be configurated as membrane-assisted techniques to carry out the extraction. These supports provide the required geometry and stability on the contact surface...

The paper describes a comprehensive study of the importance of cations to improve the efficiency and mass transfer in the electromembrane extraction for the determination of non-steroidal antiinflammatory. The procedure has been demonstrated to be adequate for the analysis of the selected non-steroidal anti-inflammatory drugs in human urine...

A selective electromembrane extraction procedure for the extraction of Enrofloxacin, Marbofloxacin and Flumequine, usually employed as antibiotic in veterinarian use, is proposed by using a chitosan biofilm, composed by 60% (w/w) chitosan and 40% (w/w) Aliquat®336, as active biopolymeric support. The interaction mechanism occurring between the...

Up to now, most electromembrane extraction methods describe the use of pure organic solvents or mixtures as supported liquid membrane. However, the need to incorporate carriers in the supported liquid membrane to achieve the extraction of high polar compounds, seems to indicate that the presence of certain additives in the organic solvent may...

In this work the presence of different pharmaceuticals at Doñana National Park (Spain) and their main entry sources (input source or entry points) have been stated over the 2011–2016 years period. Twenty-three selected pharmaceuticals (corresponding to eight therapeutic families) were evaluated in crayfish and water samples from Doñana National...

El objetivo principal de esta investigación es la determinación de la cantidad de ácido acético en diferentes vinagres comerciales mediante una valoración ácido-base para determinar el grado de acidez de los mismos, relacionarlos con las diferentes denominaciones de origen y los distintos tipos de envejecimiento. Así mismo se comprobará que...

Water pollution poses an important problem, but limited information is available about the joined effects of xenobiotics of different chemical groups to evaluate the real biological response. Procambarus clarkii (P. clarkii) has been demonstrated to be a good bioindicator for assessing the quality of aquatic ecosystems. In this work, we studied...
