Preparation of MnO2/Poly-pyrrole Nanocomposite Coating Solid Phase Microextraction Fiber and Its Extraction Performance for Polycyclic Aromatic Hydrocarbons in Environmental Water Samples
摘要
Abstract
To overcome the limitations of commercial solid phase microextraction(SPME)fiber coat-ings,including mechanical fragility,inadequate thermal stability,and restricted selectivity,this study proposes a titanium(Ti)-based manganese dioxide/polypyrrole(MnO2/PPy)nanocomposite coat-ing with enhanced performance.A hierarchical composite architecture(denoted as Ti@TiO2@SiO2NPs@MnO2/PPyNPs)was engineered by sequentially fabricating nano-pyramidal TiO2 structures on Ti wire via anodic oxidation,electrophoretic deposition of silica nanoparticles(SiO2NPs),and cyclic voltam-metry(CV)-assisted co-deposition of MnO2 and PPy nanoparticles.The morphology,chemical compo-sition,and structure of the coating were systematically characterized using scanning electron micros-copy(SEM),energy-dispersive spectroscopy(EDS),X-ray photoelectron spectroscopy(XPS),and X-ray diffraction(XRD).Under optimized conditions,the coating exhibited exceptional extraction selectivity for polycyclic aromatic hydrocarbons(PAHs),achieving a wide linear range(0.01-500μg·L-1),low detection limits(LOD,0.002-0.033 μg·L-1),high precision(relative standard devi-ation,RSD≤6.9％),and satisfactory spiked recoveries(93.0％-107％).Practical application to real water samples demonstrated its high sensitivity,robust stability,and environmental compatibility,providing a promising technical solution for efficient monitoring of trace PAHs.关键词
