Özet

A vortex assisted magnetic ionic liquid based dispersive liquid-liquid microextraction (VA-MIL-DLLME) approach was proposed using a tetrachloromanganate-based magnetic ionic liquid (MIL, as extraction solvent) for the determination and extraction of metribuzin in some plant samples by UV-Vis spectrophotometer. The MIL was prepared from a mixture of trihexyl(tetradecyl)phosphonium chloride [P-6,6,6,14(+)][Cl-] and manganese(II) chloride tetrahydrate (MnCl2.4H2O) in chloroform. Important factors for the VA-MIL-DLLME approach were optimized in detailed. The optimum conditions were: 8.0 of pH, 80 mg of the [P-6,6,6,14(+)](2)[MnCl42-] (extraction solvent), 250 mu L of ethanol (as dispersing solvent), 3 min of vortex time and 1.5 mL of 30 % NaCl (w/v) (ionic strength). Calibration graph was linear in the range of 35-800 mu g L-1 with correlation of determination 0.995. The limit of detection, limit of quantification and enrichment factor were found to be 10.6 mu g L-1, 35 mu g L-1 and 247, respectively. The VA-MIL-DLLME approach was applied for extraction and determination of metribuzin in the samples. The relative standard deviations (RSD) in the samples were less than 2.8 %. Moreover, the re-coveries were obtained in the range of 91 +/- 2-102 +/- 3 %.
