An efficient and simple analytical approach called vortex assisted reverse phase spray-based fine droplet formation liquid phase microextraction (VA-RP-SFDF-LPME) was proposed for the preconcentration and extraction of cadmium from sunflower oil, olive oil, and hazelnut oil samples. The method was environmentally friendly and easy to use, and the cadmium content was measured by flame atomic absorption spectrometry (FAAS). The LOD/LOQ values for sunflower oil, olive oil, and hazelnut oil were calculated as 2.89/9.62 μg/kg, 2.00/6.68 μg/kg, and 4.77/15.92 μg/kg, respectively. Recovery experiments showed satisfactory results, indicating the accuracy and applicability of the method for quantifying the cadmium content in these oil samples.
In this study, an efficient and simple analytical approach for the preconcentration and extraction of cadmium from sunflower oil, olive oil and hazelnut oil samples using environmentally friendly, easy and efficient vortex assisted reverse phase spray-based fine droplet formation liquid phase microextraction (VA-RP-SFDF-LPME) prior to flame atomic absorption spectrometry (FAAS) measurement was proposed. Limit of detection (LOD)/ limit of quantification (LOQ) values were calculated as 2.89/9.62 mu g/kg, 2.00/6.68 mu g/kg and 4.77/15.92 mu g/kg for sunflower oil, olive oil and hazelnut oil, respectively. Recovery experiments were carried out for the evaluation of applicability and accuracy of the developed method. Satisfactory recovery results for hazelnut oil, olive oil and sunflower oil samples were recorded in the range of 92.8 - 111.9%, 96.6 - 108.2% and 90.0 - 105.7%, respectively. These results verified that the proposed method can be accurately applied to the hazelnut oil, olive oil and sunflower oil samples to qualify/quantify their cadmium content.
