Özet
In the presented work, 1-pentanol-Graphene oxide nanocomposite was synthesised and characterised for the micro solid phase extraction of cadmium (Cd(II)) and lead (Pb(II)) at trace levels prior to their flame atomic absorption spectrometric determination. The following analytical optimisation factors were optimised: pH, adsorbent amount, sample volume, eluent type and concentration, and volume. The preconcentration factor was 15. LOQs (limit of quantification) values for Cd (II) and Pb (II) were 8.03 and 11.46 µg/kg, respectively. The validation of the presented procedure was checked by the analysing Corn bran (8433) and bitter chocolate (ERM-BD512) certified reference materials. The developed method was successfully applied to a variety of real personal care product matrices, demonstrating its robustness against complex organic backgrounds. Owing to its minimal sorbent consumption, low solvent requirement, and high enrichment capability, the proposed µ-SPE approach provides a sustainable and sensitive alternative for heavy metal monitoring in consumer products. The method was successfully applied to determination of cadmium and lead contents of some personnel care products.
