Abstract:
      In this study, magnetic polystyrene (Fe3O4@PS) microspheres were used as adsorbents in solid phase extraction combined with GC-MS to evaluate the efficiency of extracting chlorophenols (CPs) from papermaking wastewater. The novel microspheres were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD) and fourier-transform infrared spectroscopy (FT-IR). The main influence parameters of the magnetic solid-phase extraction (MSPE), such as the amount of sorbent, extraction time and elution condition, were investigated and optimized. The results demonstrated that 20 mg of sorbent, 7 min of desorption time and 2 mL of eluent solvent were chosen as the optimum conditions. Under the optimum conditions, an excellent linearity was observed in the range of 2.5~2000 μg/L. The LODs for chlorophenols were in the range of 0.076~0.207 μg/L and the correlation coefficients ranging from 0.9966~0.9994. The proposed method was successfully applied for the analysis of papermaking wastewater samples with recoveries ranging from 83.39%~109.40%. The above results demonstrated that Fe3O4@PS as a MSPE absorbent performed effective extraction efficiency and simplified operation process in the trace analysis of CPs.
