Özet
In this study, a new Solid Phase Extraction (SPE) method was developed for the detection of cobalt ions in water and food samples with High-Resolution Continuum Source Flame Atomic Absorption Spectroscopy (HR- CS FAAS). Cobalt ions were recovered and separated for the first time using grape stalk-based active carbon in this work (ACGS). Separation and preconcentration operations were carried out using the column method. Sample solution pH, eluent type and concentration, flow rates of the sample solution and eluent, sample solution volume, the influence of foreign ions, and adsorbent capacities were tested to find the best conditions for the recovery of analyte ions. The pH was set to 7.0, the extraction eluent volume was 5 mL 2 mol/L, and the sample flow rate was 4 mL/min in order to produce the best extraction possible. Under optimum conditions, the Limits of Detection (LOD) and Relative Standard Deviation (RSD) were obtained as 0.27 mu g/L and 2.3%, respectively, and the maximum adsorption capacity based on the Langmuir was found to be 8.1 mg/g. Analyte ions were added to real samples to test the method's accuracy, and the results were then compared to those of other methods and reference materials (SRM). More than a few water and food samples were successfully tested this way.
