Özet

In this work a novel and green vortex-assisted surfactant-enhanced emulsification microextraction (VA-SEEME) based on magnetic deep eutectic solvents (MDESs) was developed for the determination of chlorpyrifos in foodstuffs by UV-Vis spectrophotometric analysis. MDES (trihexyltetradecylphosphonium chloride: MnCl2: octanoic acid) was used as the extractant, non-ionic surfactant Tween-80 was used as an extraction medium, and ethanol as the eluent solvent. In the VA-MDES-SEEME procedure, a vortex was applied for agitation, and a neodymium magnet was used to separate the MDES from the aqueous solution. Under optimized conditions, a linear dynamic range was obtained in the range of 0.3–260 µg L−1 with a detection limit of 0.09 µg L−1. The intraday and interday precisions of the method, defined as relative standard deviation, ranged from 1.3 % to 2.5 %. The recovery of the spiked sample after the VA-MDES-SEEME procedure ranged from 88±6 % to 98±1 %, and the enrichment factor was obtained as 91-fold. The VA-MDES-SEEME procedure was validated by analysis of the certified reference materials including 7507a-Green Onion and 7508a-Cabbage. The VA-MDES-SEEME procedure is based on inexpensive equipment and green chemicals and is compatible with UV-Vis spectrophotometer analysis. The green profile of the VA-MDES-SEEME procedure within the scope of the current study was calculated as 0.71 using AGREE.
