Özet

This study is focused on the design of a spectrophotometric technique for the liquid–liquid microextraction (Ss-LLME) of aluminum from water and hair samples to use a supramolecular solvent. Al (III)-curcumin complex was quantitatively isolated and preconcentrated using supramolecular solvent liquid–liquid microextraction at pH 6.0. The measured molar absorptivity for the compound was 9.28 × 104 L mol−1 cm−1 at 430 nm. Beers law was applicable in the concentration range of 0.1–12.0 µg mL−1. Extraction efficiency influencing factors like solution pH (6.0), mass of chelating agent (0.1 mg), sample volume (20 mL), type and volume of supramolecular solvent (decanol, 0.1 mL), the volume of THF (0.2 mL) and matrix effect was optimized. Parameters of merit like a limit of detection (0.056 mg L−1) and limit of quantification (0.189 mg L−1), preconcentration factors (50), enrichment factor (50), and determined relative standard deviations. The new method's precision was determined by analyzing verified reference materials TMDA-64.3 fortified water and NCS ZC81002B human hair. The procedure was applied to determination of aluminum contents of hair and water samples.
