Abstract
In this paper, a new molecularly imprinted solid-phase extraction (MISPE) method was described for the determination of the chlorpyrifos in water samples. A thiol-ene based UV-cured polymer was prepared by mixing glyoxal bis (-diallyl acetal), pentaerythritol tetrakis (3-mercaptopropionate), polyethylene glycol diacrylate (PEGDA), and photoinitiator. Chlorpyrifos was added to the prepared polymer as a template analyte, and its analysis was performed by gas chromatography with mass detection (GC-MS). The influence of some analytical parameters was studied. We found that the use of the molecularly imprinted polymer (MIP) UV-cured disc provides an easy, selective, and available solution for removing chlorpyrifos from water samples.
