Özet
Magnetic solid phase extraction (M-SPE) and magnetic colloidal gel based-dispersive solid phase extraction (MCG-dSPE) methods have been developed with the Fe3O4@XAD-16 magnetic nanoparticle for preconcentration carmosine in some food samples. The effects of some parameters on preconcentration of carmoisine were investigated such as pH, amount of magnetic nanoparticle, volume of deep eutectic solvent (DES), type of desorption solvent, vortex time (for adsorption and desorption), sample volume and extraction time for both methods. Then, the recovery results of carmoisine for both methods were compared and satisfactory recoveries were obtained from the MCG-dSPE method. Under the optimum conditions for the MCG-dSPE method, the limit of detection (LOD) and limit of quantification (LOQ), preconcentration factor (PF) and enhancement factor (EF) were calculated as 0.86 mu g L-1 and 2.89 mu g L-1, 100, 103, respectively. All results showed that the developed method is a fast and good technique that can be applied to real samples for the determination of carmoisine.
