Abstract
Magnetic graphene nanocomposite was fabricated and applied to the extraction of PAHs in water, followed by GC-MS. The method showed a good linearity. The limits of detection (S/N = 3) were in a range between 0.02–14.3 ng L−1.
Highlights
Polycyclic aromatic hydrocarbons (PAHs) are a class of semivolatile organic compounds with two or more fused aromatic rings
The structures of Fe3O4/rGO nanoparticles were analysed by Fourier transform infrared (FTIR), Raman, X-ray diffraction (XRD) and scanning electron microscopy (SEM)
Paper accompanying with the synthesis of Fe3O4/rGO. It can be seen from the FTIR image of pristine GO that the signals of four groups of obvious transmission peak at 3430 cmÀ1 (O–H stretching), 1627 cmÀ1 (O–H bending vibration), 1220 cmÀ1 and 1052 cmÀ1 (C–O stretching), 1700 cmÀ1 (C]O stretching)
Summary
Polycyclic aromatic hydrocarbons (PAHs) are a class of semivolatile organic compounds with two or more fused aromatic rings. PAHs are formed by the incomplete combustion of organic matter and generated whenever fossil fuels or vegetation are burned. These environmental pollutants are ubiquitous under the in uence of atmospheric circulation and the water cycle, even in the Arctic and Antarctica in which there is almost no human activity.[1] The NHANES have shown that humans, starting from fetuses, are under the toxic effects of PAHs, which can increase the risk of adverse health effects.[2] DNA adducts in all cell types and carcinogenic PAHs and/or B[a]P in the inhaled air showed positive signi cant correlations (r 1⁄4 0.38–0.45, P < 0.001).[3] the toxicity of PAHs has justi ed their inclusion in environmental legislation worldwide. The U.S Environmental Protection Agency (EPA) developed ambient
