Abstract
- In the present study, the deep eutectic solvent-based extraction method has been developed for separation of Zn prior to ICP-OES analysis. Five different choline chloride-based deep eutectic solvents were prepared. The Zn extraction ability of DESs from milk powder and baby formulation samples which contain a high amount of milk protein was investigated. The parameters affecting the extraction efficiency such as the amount and type of solvent, extraction time and ambient temperature were optimized. Oxalic acid-based DES gave the highest yield and reproducible results and appropriate preparation criteria. It is concluded from the results that DES-oxalic can quantitatively extract Zn from milky samples. The analytical parameters such as linear calibration range, limit of detection (4.2 µg L−1) and quantification (14.1 µg L−1) were also calculated. The added-found method is successfully applied to ERM BD 150 standard reference material, and the recovery values and standard deviation values were found between the ranges of 79.4–97.21 µg L−1 and 4.1–6.31 µg L−1, respectively. The method was also applied to real samples, and the recovery values were found between 73 and 106% in the spiked samples. [ABSTRACT FROM AUTHOR]
