摘要: In this work, in-tube solid phase microextraction (in-tube SPME) coupled to capillary LC (CapLC) with diode array detection has been reported, for on-line extraction and enrichment of booster biocides (irgarol-1051 diuron) included in Water Frame Directive 2013/39/UE (WFD). The analytical performance successfully demonstrated. Furthermore, the present environmental friendliness procedure quantified by means implementation carbon footprint calculation comparison other methodologies previously reported. Under optimum conditions, method presents good linearity over range assayed, 0.05-10μg/L irgarol-1051 0.7-10μg/L diuron. LODs were 0.015μg/L 0.2μg/L diuron, respectively. Precision was also satisfactory (relative standard deviation, RSD<3.5%). proposed methodology applied monitor water samples, taking into account EQS standards these compounds. values consolidate operational efficiency (analytical performance) SPME-CapLC-DAD, general, particular determining diuron samples.
