Existe una creciente preocupación medioambiental debida la presencia de microcontaminantes orgánicos en los sistemas acuáticos. La escasa eficiencia en la degradación de contaminantes orgánicos persistentes en las plantas de tratamiento de aguas residuales convencionales basadas en procesos biológicos constituye uno de los principales fuentes de su emisión en el medio ambiente. Esto significa la liberación continua en el ciclo del agua de sustancias que aunque se encuentran en muy bajas concentraciones, han sido reconocidas como potencialmente peligrosas para el medio ambiente y la salud humana. Por tanto, para la eliminación de estas sustancias se está investigando la inclusión de un tratamiento terciario en las estaciones depuradoras de aguas residuales. En este respecto, los procesos de oxidación avanzada (POA) han sido ampliamente investigados debido a la generación de radicales hidroxilos altamente reactivos, capaces de oxidar compuestos orgánicos. Entre ellos, el proceso foto-Fenton ha demostrado ser eficaz en la eliminación de microcontaminantes. Sin embargo, todavía se necesita investigar en la operación de este proceso para su aplicación en plantas de tratamiento de aguas residuales a escala real. Este trabajo ha sido diseñado para evaluar diferentes estrategias de operación del proceso foto-Fenton como tratamiento terciario para eliminar microcontaminantes en efluentes secundarios de la industria agroalimentaria (“Cítricos del Andarax S.A.”, Almería, España) y de plantas de tratamiento de aguas residuales municipales. La evaluación se ha realizado en función de las características de las distintas matrices de agua así como por la viabilidad de escalar el proceso a niveles reales utilizando un reactor de bajo costo tipo “raceway”. Los reactores “raceway” son fotorreactores extensivos formados por canales donde el líquido es movido por un agitador de palas y que permiten tratar grandes volúmenes de agua. En resumen, el trabajo presentado en esta tesis muestra que controlar el pH durante la depuración biológica de aguas residuales de industria agro-alimentaria facilita la eliminación de microcontaminantes mediante el proceso de foto-Fenton y que reduce los costes de reactivos. Además, el exceso de fango generado durante el tratamiento biológico puede ser reducido por ultrasonicación del fango purgado y degrada la mayoría de los plaguicidas absorbidos en el fango. Por otro lado, los reactores tipo “raceway” permiten altas capacidades de tratamiento para la eliminación de microcontaminantes mediante procesos de Fenton solares como la dosificación secuencial de hierro y el uso del complejo Fe3+/EDDS, habiendo demostrado ser tratamientos eficientes en la eliminación de microcontaminates y toxicidad en efluentes secundarios de depuradoras de aguas residuales.

This book offers comprehensive information on all aspects of ELISA, starting with the fundamentals of the immune system. It also reviews the history of analytical assays prior to the advent of ELISA (enzyme-linked immunosorbent assay) and addresses the materials of choice for the fabrication of the platforms, possible biomolecular interactions, different protocols, and evaluation parameters. The book guides readers through the respective steps of the analytical assay, while also familiarizing them with the possible sources of error in the assay. It offers detailed insights into the immobilization techniques used for protein attachment, as well as methods for evaluating the assay and calculating the key parameters, such as sensitivity, specificity, accuracy and limit of detection. In addition, the book explores the advantages and shortcomings of the conventional ELISA, as well as various approaches to improving its performance. In this regard, merging and integrating other technologies with widely known ELISAs have opened new avenues for the advancement of this immunoassay. Accordingly, the book provides cutting-edge information on integrated platforms such as ELISpot, plasmonic ELISAs, sphere-/bead-based ELISAs, paper-/fiber-based ELISAs and ELISA in micro-devices.
