Abstract: En el presente estudio se ha puesto en marcha una metodología analítica para la determinación de compuestos antifloculantes en muestras de agua procedentes de distintos puertos de la isla de Gran Canaria. Para la extracción de los analitos se ha utilizado la extracción en fase sólida (SPE) con cartuchos Envirelut Pesticide. Posteriormente el extracto ha sido analizado mediante cromatografía líquida de alta resolución acoplada a un detector de absorbancia UV (HPLC-DAD). Las desviaciones standard relativas (RSDs) del método desarrollado son inferiores al 12 % para todos los compuestos en estudio. Las recuperaciones obtenidas son satisfactorias (superiores al 85%) y los límites de detección (LODs) hallados varian entre 0.007-0.4 μg/L. Finalmente el método ha sido aplicado a muestras de agua de mar procedente de diferentes puertos de la isla de Gran Canaria.
In order to study the concentration levels of the most important booster biocides in different ports of Gran Canaria island (Canary Islands), an analytical procedure was developed. The analytes studied were extracted form water samples by solid-phase extraction with an Envirelut Pesticide cartridge. After optimization of the extraction procedure, the biocides in the extract were directly determined by high performance liquid chromatography with diode array detector (HPLC-DAD). The relative standard deviations (RSDs) of the developed procedure were lesser than 12 % for all studied compounds. Satisfactory recoveries (higher than 85 %) were obtained, and the limits of detection (LODs) varied between 0.007-0.4 μg/L for all antifouling agents. The method was applied to the analysis of seawater samples from ports and marinas of G.C. island.
