Özet
In the present study, concentrations of calcium (Ca), copper (Cu), magnesium (Mg), manganese (Mn), sodium (Na), and zinc (Zn) in hardaliye samples produced in Turkey were determined by flame atomic absorption spectrometry after ultrasound probe extraction (UPE), microwave-assisted extraction (MAE), and wet extraction procedures. At present, there is limited work in the literature on UPE for the determination of trace elements in beverage samples. Our single-correlation analysis showed that the elements studied with the UPE method in hardaliye were strongly correlated with the MAE procedure. The parameters affecting the UPE experimental conditions such as ultrasound amplitude, sonication time, sample amount, extractant type, and volume were studied. Optimal experimental conditions for the extraction of the metals with the UPE procedure were as follows: 2 min of sonication; 30% amplitude; 3 mL sample volume; 5% HNO3 extraction solution; and 1 mL extractant volume for Ca, Cu, Mg, Mn, Na, and Zn in the hardaliye samples. The results in the hardaliye samples in minimum maximum mg/L with the UPE procedure were 33-63 for Ca, 0.10-0.27 for Cu, 3.9-14.4 for Mg, 1.0-3.2 for Mn, 32-58 for Na, and 0.39-1.1 for Zn. LODs were 0.0032, 0.012, 0.013, 0.009, 0.011, and 0.008 mg/L for Ca, Cu, Mg, Mn, Na, and Zn, respectively. The accuracy of the method was verified with a recovery test (in which recoveries between 95 and 110% were observed) and application to a NIST 1643e certified sample (trace elements in water). The UPE procedure was found to be fast, accurate, and simple, with fewer contaminants and lower concentrated reagent consumption in comparison with conventional extraction procedures.
