Determination of Resmethrin in Corn Silk Matrix by Gas Chromatography-Flame Ionization Detector (GC-FID)

Abstract

The use of pesticides provides benefits such as growing food products necessary for life, sustainability of production efficiency and prevention of diseases caused by pests. However, these benefits can turn into negative effects for humans and other living organisms with the use of pesticides in inappropriate doses and methods. In this study, it was aimed to determine resmethrin, which belongs to the insecticide class, by gas chromatography-flame ionization detector (GC-FID) method. Hence, a suitable temperature program was utilized to separate resmethrin at a certain retention time and satisfactory system analytical performance values were recorded under the proposed conditions. After corn silk sample was extracted using acetonitrile, analytical measurements were carried out for prepared sample to investigate the presence of resmethrin. There was no analytical signal belongs to resmethrin in blank analysis. Recovery experiments were performed using external calibration method with spiked samples at three concentrations and good percent recovery results were obtained between 93.6 – 96.9%.
