Barrado Esteban, Enrique Rodríguez Ávila, José Ángel 2019 Producción Científica Sample pretreatment is one of the most important steps in chemical analysis. Extensive clean-up procedures are normally required to remove matrix components which may interfere in the analysis. Some common strategies to these steps are based on the liquid–liquid extraction or solid phase extraction (SPE) techniques, in which the separation occurs by the analyte partition coefficient between the sample solution phase and the solid sorbent. SPE has several merits such as lower cost, higher enrichment factor and less consumption of organic solvents. application/pdf http://uvadoc.uva.es/handle/10324/38726 eng Elsevier Magnetic Materials in Separation Science info:eu-repo/semantics/bookPart TEXT UVaDOC.
