ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic compounds resulting from incomplete burning of organic materials. This work describes the successful layer‐by‐layer fabrication a novel zinc oxide nanocomposite made nanoparticles, aniline, sodium dodecyl sulfate, and modified multi‐walled carbon nanotubes on stainless steel wire by electrodeposition. The coating extraction conditions were screened, optimized, validated using factorial design central composite design, respectively. prepared nanocomposites characterized Fourier‐transform infrared spectroscopy, field‐emission scanning electron microscopy, X‐ray diffraction analysis, Brunauer‐Emmett‐Teller techniques. It featured porous structure, excellent heat stability, high capacity. also adhered well to surface. Extracting PAHs was optimized through experimental design. optimal obtained for 60 min, 30%, 30°C time, amount salt, temperature, method generally showed linear range between 0.01 1.50 µg/mL with linearity (R 2 ) 0.9902–0.9992, limits detection less than 0.003 µg/mL, limit quantification lower 0.010 relative standard deviation percent 45. Recovery values analytes in food samples varied 53.4% 110.1%. proposed employed determination some while naphthalene, anthracene, phenanthrene, benzo[a]pyrene, benz[a]anthracene detected certain samples. Overall, our research suggests as potential fiber that enables high‐capacity PAH extraction.
