Investigation on Simultaneous Determination of Deltamethrin, Carbaryl, Microcystin-LR and Benzo[a]pyrene by Online SPE-HPLC Method

Abstract:

In this paper, simultaneous analysis method for deltamethrin, carbaryl, microcystin-LR and benzo[a]pyrene in aqueous solution was established by online solid phase extraction (SPE)-HPLC technology. The target pollutants were enriched in SPE column, eluted by switching the six-way valve, separated by analytical column, and finally measured by UV-VIS Detector (UVD) and Fluorescence Detector (FLD). The results showed that online SPE-HPLC method was suitable for determination of these four organic pollutants. The correlation coefficient of the linear curve was all larger than 0.9990, and the detection limit and the limit of quantitation could also meet the Chinese standard method for drinking water (GB/T 5750-2006 and GB/T 3838-2006). This method achieved simultaneous online enrichment and efficient removal of substrate; avoided tedious manual pre-treatment process, saved the sample volume and processing time, and also had high recovery rate and sensitivity.
