Abstract: A novel planar-structure amine-functional magnetic polymer modified graphene oxide nanocomposite (NH 2 -MP@GO) was synthesized. The properties were characterized by transmission electron microscopy (TEM) and Fourier-transform infrared spectrometry (FTIR). The obtained adsorption results showed that the NH 2 -MP@GO had great adsorptive ability toward five chlorophenols (CPs), including 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), 2,3,4,6-tetrachlorophenol (2,3,4,6-TeCP) and pentachlorophenol (PCP). Based on these, an effective magnetic solid-phase extraction (MSPE) procedure coupled with high-performance liquid chromatography–tandem mass spectrometry (LC–MS/MS) for the preconcentration and determination of the five CPs in environmental water samples was developed. Various experimental parameters that could affect the extraction efficiencies had been investigated in detail. Under the optimum conditions, the enrichment factors of the method for the target CPs were found to be 1000. The proposed method was successfully applied for the analysis of environmental water samples with recoveries ranging from 86.4 to 99.8% with correlation coefficients ( R ) higher than 0.9994. Good linearities were obtained ranging from 10 to 500 ng/L for 2-CP, 5 to 500 ng/L for 2,4-DCP, 2 to 500 ng/L for 2,4,6-TeCP and 2,3,4,6-TeCP, and 1 to 500 ng/L for PCP, respectively. The limits of quantitation for the five CPs were 0.6–9.2 ng/L. It was confirmed that the planar-structure NH 2 -MP@GO was a kind of highly effective MSPE materials used for the trace CPs analyses.
