Abstract :
In this study, a simple and sensitive method was developed for preconcentration of spirotetramat (SPT) using the ionic liquidbased dispersive liquidliquid microextraction. After extracting of SPT into 1butyl3methylimidazolium hexafluorophosphate (ionic liquid), the insecticide was injected into HPLC system for determining. Under the optimum conditions, the developed method provided a linearity in the range of 0.05–2.0 µg mL1 with R2= 0.9987, and also enrichment factor was 250. The detection limit and relative standard deviation of the developed method were 0.01 µg mL1 and 2.7%, respectively. The proposed method was successfully applied to the preconcentration and determination of SPT in spiked water samples with mean recoveries 94.096.0%.
