Multivariate Simultaneous Determination of Some PAHs in Persian Gulf Oil-Contaminated Algae and Water Samples Using Miniaturized Triton X-100-Mediated Fe3O4 Nanoadsorbent and UV-Vis Detection

This research shows the development of a miniaturized solid-phase extraction method with UV-Vis detection for simultaneous determination dibenzofuran, fluoranthene and phenanthrene using chemometrics approaches. After synthesis Fe3O4 nanoparticles (Fe3O4 NPs), surface was modified by Triton X100 coating. The influence solvent volume, concentration X100, time, sample pH were studied optimized. Due to high spectral overlapping, resolving ternary mixtures targets classical analytical methods is impossible. Therefore, recorded spectra transformed continuous wavelet transform then subjected artificial neural networks (ANNs). Db4 mother used as better wavelet. For analytes, comparison feed-forward back-propagation radial basis function accomplished. calibration graphs showed linearity in ranges 2.4–250 ng mL−1, 50–3750 48–5000 mL−1 limit 0.58, 9.5 12.5 under optimal conditions phenanthrene, fluoranthene, respectively. quantitation achieved at 3.52 16.35 31.3 involving TX-100-coated NPs liquid phase analyte extraction, followed ethanol desorption detection, successfully applied polycyclic aromatic hydrocarbons oil-field water algae samples.
