Sažetak
A simple, sensitive, and rapid dispersive liquid-liquid microextraction (DLLME) method is
developed for the preconcentration of silver ions prior to determination by flame atomic absorption
spectrometry (FAAS). In this work, 1-phenyl-1,2-propanedione-2-oximethiosemicarbazone (PPDOT), chloroform, and methanol are used as the complexing agent, extraction solvent, and disperser solvent,
respectively. The effects of different analytical parameters on the complex formation and the extrac-tion efficiency are investigated and optimized. The effects of interfering ions on the determination of silver(I) are also examined. Under the optimized conditions, a linear calibration curve was achieved in the range of 0.60−120.0 µg L−1, with the detection limit of 0.61 µg L−1. The pre-concentration factor calculated as the ratio of the slopes of the calibration graphs with and without the pre-concentration was 35.5. The relative standard deviations (RSDs) for the silver(I) determinations were below 3 %. The proposed separation
procedure was successfully applied to the determination of silver(I) in natural water and photographic film samples with satisfactory results (recoveries > 95 %).
