Abstract
In this study, dispersive liquid- liquid microextraction based on solidification of floating organic drop- UV- Vis spectrophotometry is used for the extraction and determination of cadmium in saffron samples. Ethanol as the disperser solvent, 1- undecanol as the extractant solvent and acetone as dilution solvent were used. The studies showed that the type and volume of disperser solvent, extractant solvent and dilution solvent has a significant effect in the extraction efficiency. Under the optimal conditions, detection limit of 0.0005 μg.mL-1 was obtained. The procedure was applied to saffron samples of Torbate heydariyeh, Ghaenat and Bakharz and the recovery percent for the saffron samples contaminated with 0.1 μg/mL of cadmium was obtained.
