A method using graphene aerogel solid-phase extraction combined with gas chromatography-mass spectrometry was developed for determination of three organophosphorus pesticides. The method showed good linearity and accuracy in the analysis of target analytes.
In this study, a method was developed for determination of three organophosphorus pesticides (OPPs) using graphene aerogel solid-phase extraction (SPE) combined with gas chromatography-mass spectrometry (GC-MS). The experimental results showed that the target analytes could be extracted on packed SPE cartridges and then eluted with tetrahydrofuran. The final sample solution was analyzed by GC-MS, which demonstrated good linearity between 0.5 and 500 mu g L-1 with a correlation coefficient (r) of 0.9991-0.9998. The limits of detection (SIN = 3) and the limits of quantification (SIN = 10) for the three OPPs ranged from 0.38 to 0.82 mu g L-1 and 1.32 to 2.75 mu g L-1, respectively. The accuracy of the proposed method was evaluated by measuring the recovery of the spiked samples, which ranged from 91.2 to 103.7%, with relative standard deviations of 2.1-7.2%. This method was successfully applied for the determination of the target analytes in water samples taken from tap, wetlands and canal water.
