Özet
This study investigates a new approach to synthesizing molybdenum diselenide nanoflowers doped on metalorganic frameworks-graphene oxide (GO/MOF-199/MoSe2) nanocomposite. The nanocomposite has been used for chromium speciation analysis. Various analytical methods, such as Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and fieldemission scanning electron microscopy (FE-SEM), validated the proper preparation and unique structural properties of the nanocomposite. Optimizations were conducted on several analytical parameters, including pH (9.0), ligand (1-(2-pyridylazo)-2-naphthol (PAN)), adsorbent amount (15 mg), sample and eluent volumes (30 and 2 mL), and the interference effects. The method shows outstanding sensitivity, accuracy, and efficiency, as shown by low detection and quantification limits of Cr(III) (0.11 and 0.39 mu g L -1 ) and a relatively low RSD (6.5%). The proposed method was applied to natural water, wastewater samples, and certified reference materials (CRMs) to demonstrate its adaptability and usefulness in various environmental samples.
